+ =================================
+ INTERNAL KERNEL ABI FOR FR-V ARCH
+ =================================
+
+The internal FRV kernel ABI is not quite the same as the userspace ABI. A number of the registers
+are used for special purposed, and the ABI is not consistent between modules vs core, and MMU vs
+no-MMU.
+
+This partly stems from the fact that FRV CPUs do not have a separate supervisor stack pointer, and
+most of them do not have any scratch registers, thus requiring at least one general purpose
+register to be clobbered in such an event. Also, within the kernel core, it is possible to simply
+jump or call directly between functions using a relative offset. This cannot be extended to modules
+for the displacement is likely to be too far. Thus in modules the address of a function to call
+must be calculated in a register and then used, requiring two extra instructions.
+
+This document has the following sections:
+
+ (*) System call register ABI
+ (*) CPU operating modes
+ (*) Internal kernel-mode register ABI
+ (*) Internal debug-mode register ABI
+ (*) Virtual interrupt handling
+
+
+========================
+SYSTEM CALL REGISTER ABI
+========================
+
+When a system call is made, the following registers are effective:
+
+ REGISTERS CALL RETURN
+ =============== ======================= =======================
+ GR7 System call number Preserved
+ GR8 Syscall arg #1 Return value
+ GR9-GR13 Syscall arg #2-6 Preserved
+
+
+===================
+CPU OPERATING MODES
+===================
+
+The FR-V CPU has three basic operating modes. In order of increasing capability:
+
+ (1) User mode.
+
+ Basic userspace running mode.
+
+ (2) Kernel mode.
+
+ Normal kernel mode. There are many additional control registers available that may be
+ accessed in this mode, in addition to all the stuff available to user mode. This has two
+ submodes:
+
+ (a) Exceptions enabled (PSR.T == 1).
+
+ Exceptions will invoke the appropriate normal kernel mode handler. On entry to the
+ handler, the PSR.T bit will be cleared.
+
+ (b) Exceptions disabled (PSR.T == 0).
+
+ No exceptions or interrupts may happen. Any mandatory exceptions will cause the CPU to
+ halt unless the CPU is told to jump into debug mode instead.
+
+ (3) Debug mode.
+
+ No exceptions may happen in this mode. Memory protection and management exceptions will be
+ flagged for later consideration, but the exception handler won't be invoked. Debugging traps
+ such as hardware breakpoints and watchpoints will be ignored. This mode is entered only by
+ debugging events obtained from the other two modes.
+
+ All kernel mode registers may be accessed, plus a few extra debugging specific registers.
+
+
+=================================
+INTERNAL KERNEL-MODE REGISTER ABI
+=================================
+
+There are a number of permanent register assignments that are set up by entry.S in the exception
+prologue. Note that there is a complete set of exception prologues for each of user->kernel
+transition and kernel->kernel transition. There are also user->debug and kernel->debug mode
+transition prologues.
+
+
+ REGISTER FLAVOUR USE
+ =============== ======= ====================================================
+ GR1 Supervisor stack pointer
+ GR15 Current thread info pointer
+ GR16 GP-Rel base register for small data
+ GR28 Current exception frame pointer (__frame)
+ GR29 Current task pointer (current)
+ GR30 Destroyed by kernel mode entry
+ GR31 NOMMU Destroyed by debug mode entry
+ GR31 MMU Destroyed by TLB miss kernel mode entry
+ CCR.ICC2 Virtual interrupt disablement tracking
+ CCCR.CC3 Cleared by exception prologue (atomic op emulation)
+ SCR0 MMU See mmu-layout.txt.
+ SCR1 MMU See mmu-layout.txt.
+ SCR2 MMU Save for EAR0 (destroyed by icache insns in debug mode)
+ SCR3 MMU Save for GR31 during debug exceptions
+ DAMR/IAMR NOMMU Fixed memory protection layout.
+ DAMR/IAMR MMU See mmu-layout.txt.
+
+
+Certain registers are also used or modified across function calls:
+
+ REGISTER CALL RETURN
+ =============== =============================== ===============================
+ GR0 Fixed Zero -
+ GR2 Function call frame pointer
+ GR3 Special Preserved
+ GR3-GR7 - Clobbered
+ GR8 Function call arg #1 Return value (or clobbered)
+ GR9 Function call arg #2 Return value MSW (or clobbered)
+ GR10-GR13 Function call arg #3-#6 Clobbered
+ GR14 - Clobbered
+ GR15-GR16 Special Preserved
+ GR17-GR27 - Preserved
+ GR28-GR31 Special Only accessed explicitly
+ LR Return address after CALL Clobbered
+ CCR/CCCR - Mostly Clobbered
+
+
+================================
+INTERNAL DEBUG-MODE REGISTER ABI
+================================
+
+This is the same as the kernel-mode register ABI for functions calls. The difference is that in
+debug-mode there's a different stack and a different exception frame. Almost all the global
+registers from kernel-mode (including the stack pointer) may be changed.
+
+ REGISTER FLAVOUR USE
+ =============== ======= ====================================================
+ GR1 Debug stack pointer
+ GR16 GP-Rel base register for small data
+ GR31 Current debug exception frame pointer (__debug_frame)
+ SCR3 MMU Saved value of GR31
+
+
+Note that debug mode is able to interfere with the kernel's emulated atomic ops, so it must be
+exceedingly careful not to do any that would interact with the main kernel in this regard. Hence
+the debug mode code (gdbstub) is almost completely self-contained. The only external code used is
+the sprintf family of functions.
+
+Futhermore, break.S is so complicated because single-step mode does not switch off on entry to an
+exception. That means unless manually disabled, single-stepping will blithely go on stepping into
+things like interrupts. See gdbstub.txt for more information.
+
+
+==========================
+VIRTUAL INTERRUPT HANDLING
+==========================
+
+Because accesses to the PSR is so slow, and to disable interrupts we have to access it twice (once
+to read and once to write), we don't actually disable interrupts at all if we don't have to. What
+we do instead is use the ICC2 condition code flags to note virtual disablement, such that if we
+then do take an interrupt, we note the flag, really disable interrupts, set another flag and resume
+execution at the point the interrupt happened. Setting condition flags as a side effect of an
+arithmetic or logical instruction is really fast. This use of the ICC2 only occurs within the
+kernel - it does not affect userspace.
+
+The flags we use are:
+
+ (*) CCR.ICC2.Z [Zero flag]
+
+ Set to virtually disable interrupts, clear when interrupts are virtually enabled. Can be
+ modified by logical instructions without affecting the Carry flag.
+
+ (*) CCR.ICC2.C [Carry flag]
+
+ Clear to indicate hardware interrupts are really disabled, set otherwise.
+
+
+What happens is this:
+
+ (1) Normal kernel-mode operation.
+
+ ICC2.Z is 0, ICC2.C is 1.
+
+ (2) An interrupt occurs. The exception prologue examines ICC2.Z and determines that nothing needs
+ doing. This is done simply with an unlikely BEQ instruction.
+
+ (3) The interrupts are disabled (local_irq_disable)
+
+ ICC2.Z is set to 1.
+
+ (4) If interrupts were then re-enabled (local_irq_enable):
+
+ ICC2.Z would be set to 0.
+
+ A TIHI #2 instruction (trap #2 if condition HI - Z==0 && C==0) would be used to trap if
+ interrupts were now virtually enabled, but physically disabled - which they're not, so the
+ trap isn't taken. The kernel would then be back to state (1).
+
+ (5) An interrupt occurs. The exception prologue examines ICC2.Z and determines that the interrupt
+ shouldn't actually have happened. It jumps aside, and there disabled interrupts by setting
+ PSR.PIL to 14 and then it clears ICC2.C.
+
+ (6) If interrupts were then saved and disabled again (local_irq_save):
+
+ ICC2.Z would be shifted into the save variable and masked off (giving a 1).
+
+ ICC2.Z would then be set to 1 (thus unchanged), and ICC2.C would be unaffected (ie: 0).
+
+ (7) If interrupts were then restored from state (6) (local_irq_restore):
+
+ ICC2.Z would be set to indicate the result of XOR'ing the saved value (ie: 1) with 1, which
+ gives a result of 0 - thus leaving ICC2.Z set.
+
+ ICC2.C would remain unaffected (ie: 0).
+
+ A TIHI #2 instruction would be used to again assay the current state, but this would do
+ nothing as Z==1.
+
+ (8) If interrupts were then enabled (local_irq_enable):
+
+ ICC2.Z would be cleared. ICC2.C would be left unaffected. Both flags would now be 0.
+
+ A TIHI #2 instruction again issued to assay the current state would then trap as both Z==0
+ [interrupts virtually enabled] and C==0 [interrupts really disabled] would then be true.
+
+ (9) The trap #2 handler would simply enable hardware interrupts (set PSR.PIL to 0), set ICC2.C to
+ 1 and return.
+
+(10) Immediately upon returning, the pending interrupt would be taken.
+
+(11) The interrupt handler would take the path of actually processing the interrupt (ICC2.Z is
+ clear, BEQ fails as per step (2)).
+
+(12) The interrupt handler would then set ICC2.C to 1 since hardware interrupts are definitely
+ enabled - or else the kernel wouldn't be here.
+
+(13) On return from the interrupt handler, things would be back to state (1).
+
+This trap (#2) is only available in kernel mode. In user mode it will result in SIGILL.

+Kernel driver f71805f
+=====================
+
+Supported chips:
+ * Fintek F71805F/FG
+ Prefix: 'f71805f'
+ Addresses scanned: none, address read from Super I/O config space
+ Datasheet: Provided by Fintek on request
+
+Author: Jean Delvare <khali@linux-fr.org>
+
+Thanks to Denis Kieft from Barracuda Networks for the donation of a
+test system (custom Jetway K8M8MS motherboard, with CPU and RAM) and
+for providing initial documentation.
+
+Thanks to Kris Chen from Fintek for answering technical questions and
+providing additional documentation.
+
+Thanks to Chris Lin from Jetway for providing wiring schematics and
+anwsering technical questions.
+
+
+Description
+-----------
+
+The Fintek F71805F/FG Super I/O chip includes complete hardware monitoring
+capabilities. It can monitor up to 9 voltages (counting its own power
+source), 3 fans and 3 temperature sensors.
+
+This chip also has fan controlling features, using either DC or PWM, in
+three different modes (one manual, two automatic). The driver doesn't
+support these features yet.
+
+The driver assumes that no more than one chip is present, which seems
+reasonable.
+
+
+Voltage Monitoring
+------------------
+
+Voltages are sampled by an 8-bit ADC with a LSB of 8 mV. The supported
+range is thus from 0 to 2.040 V. Voltage values outside of this range
+need external resistors. An exception is in0, which is used to monitor
+the chip's own power source (+3.3V), and is divided internally by a
+factor 2.
+
+The two LSB of the voltage limit registers are not used (always 0), so
+you can only set the limits in steps of 32 mV (before scaling).
+
+The wirings and resistor values suggested by Fintek are as follow:
+
+ pin expected
+ name use R1 R2 divider raw val.
+
+in0 VCC VCC3.3V int. int. 2.00 1.65 V
+in1 VIN1 VTT1.2V 10K - 1.00 1.20 V
+in2 VIN2 VRAM 100K 100K 2.00 ~1.25 V (1)
+in3 VIN3 VCHIPSET 47K 100K 1.47 2.24 V (2)
+in4 VIN4 VCC5V 200K 47K 5.25 0.95 V
+in5 VIN5 +12V 200K 20K 11.00 1.05 V
+in6 VIN6 VCC1.5V 10K - 1.00 1.50 V
+in7 VIN7 VCORE 10K - 1.00 ~1.40 V (1)
+in8 VIN8 VSB5V 200K 47K 1.00 0.95 V
+
+(1) Depends on your hardware setup.
+(2) Obviously not correct, swapping R1 and R2 would make more sense.
+
+These values can be used as hints at best, as motherboard manufacturers
+are free to use a completely different setup. As a matter of fact, the
+Jetway K8M8MS uses a significantly different setup. You will have to
+find out documentation about your own motherboard, and edit sensors.conf
+accordingly.
+
+Each voltage measured has associated low and high limits, each of which
+triggers an alarm when crossed.
+
+
+Fan Monitoring
+--------------
+
+Fan rotation speeds are reported as 12-bit values from a gated clock
+signal. Speeds down to 366 RPM can be measured. There is no theoretical
+high limit, but values over 6000 RPM seem to cause problem. The effective
+resolution is much lower than you would expect, the step between different
+register values being 10 rather than 1.
+
+The chip assumes 2 pulse-per-revolution fans.
+
+An alarm is triggered if the rotation speed drops below a programmable
+limit or is too low to be measured.
+
+
+Temperature Monitoring
+----------------------
+
+Temperatures are reported in degrees Celsius. Each temperature measured
+has a high limit, those crossing triggers an alarm. There is an associated
+hysteresis value, below which the temperature has to drop before the
+alarm is cleared.
+
+All temperature channels are external, there is no embedded temperature
+sensor. Each channel can be used for connecting either a thermal diode
+or a thermistor. The driver reports the currently selected mode, but
+doesn't allow changing it. In theory, the BIOS should have configured
+everything properly.

3. Configuring Kprobes
When configuring the kernel using make menuconfig/xconfig/oldconfig,
-ensure that CONFIG_KPROBES is set to "y". Under "Kernel hacking",
-look for "Kprobes". You may have to enable "Kernel debugging"
-(CONFIG_DEBUG_KERNEL) before you can enable Kprobes.
+ensure that CONFIG_KPROBES is set to "y". Under "Instrumentation
+Support", look for "Kprobes".
+
+So that you can load and unload Kprobes-based instrumentation modules,
+make sure "Loadable module support" (CONFIG_MODULES) and "Module
+unloading" (CONFIG_MODULE_UNLOAD) are set to "y".
You may also want to ensure that CONFIG_KALLSYMS and perhaps even
CONFIG_KALLSYMS_ALL are set to "y", since kallsyms_lookup_name()
5. Kprobes Features and Limitations
-As of Linux v2.6.12, Kprobes allows multiple probes at the same
-address. Currently, however, there cannot be multiple jprobes on
-the same function at the same time.
+Kprobes allows multiple probes at the same address. Currently,
+however, there cannot be multiple jprobes on the same function at
+the same time.
In general, you can install a probe anywhere in the kernel.
In particular, you can probe interrupt handlers. Known exceptions
are discussed in this section.
-For obvious reasons, it's a bad idea to install a probe in
-the code that implements Kprobes (mostly kernel/kprobes.c and
-arch/*/kernel/kprobes.c). A patch in the v2.6.13 timeframe instructs
-Kprobes to reject such requests.
+The register_*probe functions will return -EINVAL if you attempt
+to install a probe in the code that implements Kprobes (mostly
+kernel/kprobes.c and arch/*/kernel/kprobes.c, but also functions such
+as do_page_fault and notifier_call_chain).
If you install a probe in an inline-able function, Kprobes makes
no attempt to chase down all inline instances of the function and
Kprobes makes no attempt to prevent probe handlers from stepping on
each other -- e.g., probing printk() and then calling printk() from a
-probe handler. As of Linux v2.6.12, if a probe handler hits a probe,
-that second probe's handlers won't be run in that instance.
-
-In Linux v2.6.12 and previous versions, Kprobes' data structures are
-protected by a single lock that is held during probe registration and
-unregistration and while handlers are run. Thus, no two handlers
-can run simultaneously. To improve scalability on SMP systems,
-this restriction will probably be removed soon, in which case
-multiple handlers (or multiple instances of the same handler) may
-run concurrently on different CPUs. Code your handlers accordingly.
-
-Kprobes does not use semaphores or allocate memory except during
+probe handler. If a probe handler hits a probe, that second probe's
+handlers won't be run in that instance, and the kprobe.nmissed member
+of the second probe will be incremented.
+
+As of Linux v2.6.15-rc1, multiple handlers (or multiple instances of
+the same handler) may run concurrently on different CPUs.
+
+Kprobes does not use mutexes or allocate memory except during
registration and unregistration.
Probe handlers are run with preemption disabled. Depending on the
(As far as we can tell, __builtin_return_address() is used only
for instrumentation and error reporting.)
-If the number of times a function is called does not match the
-number of times it returns, registering a return probe on that
-function may produce undesirable results. We have the do_exit()
-and do_execve() cases covered. do_fork() is not an issue. We're
-unaware of other specific cases where this could be a problem.

+If, upon entry to or exit from a function, the CPU is running on

+
+1) Overview
+-----------
+Most legacy operating system kernels support an abstraction of threads
+as multiple execution contexts within a process. These kernels provide
+special resources and mechanisms to maintain these "threads". The Linux
+kernel, in a clever and simple manner, does not make distinction
+between processes and "threads". The kernel allows processes to share
+resources and thus they can achieve legacy "threads" behavior without
+requiring additional data structures and mechanisms in the kernel. The
+power of implementing threads in this manner comes not only from
+its simplicity but also from allowing application programmers to work
+outside the confinement of all-or-nothing shared resources of legacy
+threads. On Linux, at the time of thread creation using the clone system
+call, applications can selectively choose which resources to share
+between threads.
+
+unshare system call adds a primitive to the Linux thread model that
+allows threads to selectively 'unshare' any resources that were being
+shared at the time of their creation. unshare was conceptualized by
+Al Viro in the August of 2000, on the Linux-Kernel mailing list, as part
+of the discussion on POSIX threads on Linux. unshare augments the
+usefulness of Linux threads for applications that would like to control
+shared resources without creating a new process. unshare is a natural
+addition to the set of available primitives on Linux that implement
+the concept of process/thread as a virtual machine.
+
+2) Benefits
+-----------
+unshare would be useful to large application frameworks such as PAM
+where creating a new process to control sharing/unsharing of process
+resources is not possible. Since namespaces are shared by default
+when creating a new process using fork or clone, unshare can benefit
+even non-threaded applications if they have a need to disassociate
+from default shared namespace. The following lists two use-cases
+where unshare can be used.
+
+2.1 Per-security context namespaces
+-----------------------------------
+unshare can be used to implement polyinstantiated directories using
+the kernel's per-process namespace mechanism. Polyinstantiated directories,
+such as per-user and/or per-security context instance of /tmp, /var/tmp or
+per-security context instance of a user's home directory, isolate user
+processes when working with these directories. Using unshare, a PAM
+module can easily setup a private namespace for a user at login.
+Polyinstantiated directories are required for Common Criteria certification
+with Labeled System Protection Profile, however, with the availability
+of shared-tree feature in the Linux kernel, even regular Linux systems
+can benefit from setting up private namespaces at login and
+polyinstantiating /tmp, /var/tmp and other directories deemed
+appropriate by system administrators.
+
+2.2 unsharing of virtual memory and/or open files
+-------------------------------------------------
+Consider a client/server application where the server is processing
+client requests by creating processes that share resources such as
+virtual memory and open files. Without unshare, the server has to
+decide what needs to be shared at the time of creating the process
+which services the request. unshare allows the server an ability to
+disassociate parts of the context during the servicing of the
+request. For large and complex middleware application frameworks, this
+ability to unshare after the process was created can be very
+useful.
+
+3) Cost
+-------
+In order to not duplicate code and to handle the fact that unshare
+works on an active task (as opposed to clone/fork working on a newly
+allocated inactive task) unshare had to make minor reorganizational
+changes to copy_* functions utilized by clone/fork system call.
+There is a cost associated with altering existing, well tested and
+stable code to implement a new feature that may not get exercised
+extensively in the beginning. However, with proper design and code
+review of the changes and creation of an unshare test for the LTP
+the benefits of this new feature can exceed its cost.
+
+4) Requirements
+---------------
+unshare reverses sharing that was done using clone(2) system call,
+so unshare should have a similar interface as clone(2). That is,
+since flags in clone(int flags, void *stack) specifies what should
+be shared, similar flags in unshare(int flags) should specify
+what should be unshared. Unfortunately, this may appear to invert
+the meaning of the flags from the way they are used in clone(2).
+However, there was no easy solution that was less confusing and that
+allowed incremental context unsharing in future without an ABI change.
+
+unshare interface should accommodate possible future addition of
+new context flags without requiring a rebuild of old applications.
+If and when new context flags are added, unshare design should allow
+incremental unsharing of those resources on an as needed basis.
+
+5) Functional Specification
+---------------------------
+NAME
+ unshare - disassociate parts of the process execution context
+
+SYNOPSIS
+ #include <sched.h>
+
+ int unshare(int flags);
+
+DESCRIPTION
+ unshare allows a process to disassociate parts of its execution
+ context that are currently being shared with other processes. Part
+ of execution context, such as the namespace, is shared by default
+ when a new process is created using fork(2), while other parts,
+ such as the virtual memory, open file descriptors, etc, may be
+ shared by explicit request to share them when creating a process
+ using clone(2).
+
+ The main use of unshare is to allow a process to control its
+ shared execution context without creating a new process.
+
+ The flags argument specifies one or bitwise-or'ed of several of
+ the following constants.
+
+ CLONE_FS
+ If CLONE_FS is set, file system information of the caller
+ is disassociated from the shared file system information.
+
+ CLONE_FILES
+ If CLONE_FILES is set, the file descriptor table of the
+ caller is disassociated from the shared file descriptor
+ table.
+
+ CLONE_NEWNS
+ If CLONE_NEWNS is set, the namespace of the caller is
+ disassociated from the shared namespace.
+
+ CLONE_VM
+ If CLONE_VM is set, the virtual memory of the caller is
+ disassociated from the shared virtual memory.
+
+RETURN VALUE
+ On success, zero returned. On failure, -1 is returned and errno is
+
+ERRORS
+ EPERM CLONE_NEWNS was specified by a non-root process (process
+ without CAP_SYS_ADMIN).
+
+ ENOMEM Cannot allocate sufficient memory to copy parts of caller's
+ context that need to be unshared.
+
+ EINVAL Invalid flag was specified as an argument.
+
+CONFORMING TO
+ The unshare() call is Linux-specific and should not be used
+ in programs intended to be portable.
+
+SEE ALSO
+ clone(2), fork(2)
+
+6) High Level Design
+--------------------
+Depending on the flags argument, the unshare system call allocates
+appropriate process context structures, populates it with values from
+the current shared version, associates newly duplicated structures
+with the current task structure and releases corresponding shared
+versions. Helper functions of clone (copy_*) could not be used
+directly by unshare because of the following two reasons.
+ 1) clone operates on a newly allocated not-yet-active task
+ structure, where as unshare operates on the current active
+ task. Therefore unshare has to take appropriate task_lock()
+ before associating newly duplicated context structures
+ 2) unshare has to allocate and duplicate all context structures
+ that are being unshared, before associating them with the
+ current task and releasing older shared structures. Failure
+ do so will create race conditions and/or oops when trying
+ to backout due to an error. Consider the case of unsharing
+ both virtual memory and namespace. After successfully unsharing
+ vm, if the system call encounters an error while allocating
+ new namespace structure, the error return code will have to
+ reverse the unsharing of vm. As part of the reversal the
+ system call will have to go back to older, shared, vm
+ structure, which may not exist anymore.
+
+Therefore code from copy_* functions that allocated and duplicated
+current context structure was moved into new dup_* functions. Now,
+copy_* functions call dup_* functions to allocate and duplicate
+appropriate context structures and then associate them with the
+task structure that is being constructed. unshare system call on
+the other hand performs the following:
+ 1) Check flags to force missing, but implied, flags
+ 2) For each context structure, call the corresponding unshare
+ helper function to allocate and duplicate a new context
+ structure, if the appropriate bit is set in the flags argument.
+ 3) If there is no error in allocation and duplication and there
+ are new context structures then lock the current task structure,
+ associate new context structures with the current task structure,
+ and release the lock on the current task structure.
+ 4) Appropriately release older, shared, context structures.
+
+7) Low Level Design
+-------------------
+Implementation of unshare can be grouped in the following 4 different
+items:
+ a) Reorganization of existing copy_* functions
+ b) unshare system call service function
+ c) unshare helper functions for each different process context
+ d) Registration of system call number for different architectures
+
+ 7.1) Reorganization of copy_* functions
+ Each copy function such as copy_mm, copy_namespace, copy_files,
+ etc, had roughly two components. The first component allocated
+ and duplicated the appropriate structure and the second component
+ linked it to the task structure passed in as an argument to the copy
+ function. The first component was split into its own function.
+ These dup_* functions allocated and duplicated the appropriate
+ context structure. The reorganized copy_* functions invoked
+ their corresponding dup_* functions and then linked the newly
+ duplicated structures to the task structure with which the
+ copy function was called.
+
+ 7.2) unshare system call service function
+ * Check flags
+ Force implied flags. If CLONE_THREAD is set force CLONE_VM.
+ If CLONE_VM is set, force CLONE_SIGHAND. If CLONE_SIGHAND is
+ set and signals are also being shared, force CLONE_THREAD. If
+ CLONE_NEWNS is set, force CLONE_FS.
+ * For each context flag, invoke the corresponding unshare_*
+ helper routine with flags passed into the system call and a
+ reference to pointer pointing the new unshared structure
+ * If any new structures are created by unshare_* helper
+ functions, take the task_lock() on the current task,
+ modify appropriate context pointers, and release the
+ task lock.
+ * For all newly unshared structures, release the corresponding
+ older, shared, structures.
+
+ 7.3) unshare_* helper functions
+ For unshare_* helpers corresponding to CLONE_SYSVSEM, CLONE_SIGHAND,
+ and CLONE_THREAD, return -EINVAL since they are not implemented yet.
+ For others, check the flag value to see if the unsharing is
+ required for that structure. If it is, invoke the corresponding
+ dup_* function to allocate and duplicate the structure and return
+ a pointer to it.
+
+ 7.4) Appropriately modify architecture specific code to register the
+ the new system call.
+
+8) Test Specification
+---------------------
+The test for unshare should test the following:
+ 1) Valid flags: Test to check that clone flags for signal and
+ signal handlers, for which unsharing is not implemented
+ yet, return -EINVAL.
+ 2) Missing/implied flags: Test to make sure that if unsharing
+ namespace without specifying unsharing of filesystem, correctly
+ unshares both namespace and filesystem information.
+ 3) For each of the four (namespace, filesystem, files and vm)
+ supported unsharing, verify that the system call correctly
+ unshares the appropriate structure. Verify that unsharing
+ them individually as well as in combination with each
+ other works as expected.
+ 4) Concurrent execution: Use shared memory segments and futex on
+ an address in the shm segment to synchronize execution of
+ about 10 threads. Have a couple of threads execute execve,
+ a couple _exit and the rest unshare with different combination
+ of flags. Verify that unsharing is performed as expected and
+ that there are no oops or hangs.
+
+9) Future Work
+--------------
+The current implementation of unshare does not allow unsharing of
+signals and signal handlers. Signals are complex to begin with and
+to unshare signals and/or signal handlers of a currently running
+process is even more complex. If in the future there is a specific
+need to allow unsharing of signals and/or signal handlers, it can
+be incrementally added to unshare without affecting legacy
+applications using unshare.

* because tsk is already marked PF_EXITING, so attach_task() won't
* mess with it, or task is a failed fork, never visible to attach_task.
+ *
+ * Hack:
+ *
+ * Set the exiting tasks cpuset to the root cpuset (top_cpuset).
+ *
+ * Don't leave a task unable to allocate memory, as that is an
+ * accident waiting to happen should someone add a callout in
+ * do_exit() after the cpuset_exit() call that might allocate.
+ * If a task tries to allocate memory with an invalid cpuset,
+ * it will oops in cpuset_update_task_memory_state().
+ *
+ * We call cpuset_exit() while the task is still competent to
+ * handle notify_on_release(), then leave the task attached to
+ * the root cpuset (top_cpuset) for the remainder of its exit.
+ *
+ * To do this properly, we would increment the reference count on
+ * top_cpuset, and near the very end of the kernel/exit.c do_exit()
+ * code we would add a second cpuset function call, to drop that
+ * reference. This would just create an unnecessary hot spot on
+ * the top_cpuset reference count, to no avail.
+ *
+ * Normally, holding a reference to a cpuset without bumping its
+ * count is unsafe. The cpuset could go away, or someone could
+ * attach us to a different cpuset, decrementing the count on
+ * the first cpuset that we never incremented. But in this case,
+ * top_cpuset isn't going away, and either task has PF_EXITING set,
+ * which wards off any attach_task() attempts, or task is a failed
+ * fork, never visible to attach_task.
+ *
+ * Another way to do this would be to set the cpuset pointer
+ * to NULL here, and check in cpuset_update_task_memory_state()
+ * for a NULL pointer. This hack avoids that NULL check, for no
+ * cost (other than this way too long comment ;).
