vfs: make O_PATH file descriptors usable for 'fchdir()'

We already use them for openat() and friends, but fchdir() also wants to
be able to use O_PATH file descriptors.  This should make it comparable
to the O_SEARCH of Solaris.  In particular, O_PATH allows you to access
(not-quite-open) a directory you don't have read persmission to, only
execute permission.

Noticed during development of multithread support for ksh93.

vfs: make O_PATH file descriptors usable for 'fstat()'

We already use them for openat() and friends, but fstat() also wants to
be able to use O_PATH file descriptors.  This should make it more
directly comparable to the O_SEARCH of Solaris.

Note that you could already do the same thing with "fstatat()" and an
empty path, but just doing "fstat()" directly is simpler and faster, so
there is no reason not to just allow it directly.

See also commit 332a2e1244bd, which did the same thing for fchdir, for
the same reasons.

drivers/base: add bus for System-on-Chip devices

Traditionally, any System-on-Chip based platform creates a flat list
of platform_devices directly under /sys/devices/platform.

In order to give these some better structure, this introduces a new
bus type for soc_devices that are registered with the new
soc_device_register() function.  All devices that are on the same
chip should then be registered as child devices of the soc device.

The soc bus also exports a few standardised device attributes which
allow user space to query the specific type of soc.

compiler-gcc.h: Add gcc-recommended GCC_VERSION macro

Throughout compiler*.h, many version checks are made.  These can be
simplified by using the macro that gcc's documentation recommends.
However, my primary reason for adding this is that I need bug-check
macros that are enabled at certain gcc versions and it's cleaner to use
this macro than the tradition method:

  #if __GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ => 2)

If you add patch level, it gets this ugly:

  #if __GNUC__ > 4 || (__GNUC__ == 4 && (__GNUC_MINOR__ > 2 || \
      __GNUC_MINOR__ == 2 __GNUC_PATCHLEVEL__ >= 1))

As opposed to:

  #if GCC_VERSION >= 40201

While having separate headers for gcc 3 & 4 eliminates some of this
verbosity, they can still be cleaned up by this.

ftrace: Make all inline tags also include notrace

Commit 5963e317b1e9d2a ("ftrace/x86: Do not change stacks in DEBUG when
calling lockdep") prevented lockdep calls from the int3 breakpoint handler
from reseting the stack if a function that was called was in the process
of being converted for tracing and had a breakpoint on it. The idea is,
before calling the lockdep code, do a load_idt() to the special IDT that
kept the breakpoint stack from reseting. This worked well as a quick fix
for this kernel release, until a certain config caused a lockup in the
function tracer start up tests.

Investigating it, I found that the load_idt that was used to prevent
the int3 from changing stacks was itself being traced!

Even though the config had CONFIG_OPTIMIZE_INLINING disabled, and
all 'inline' tags were set to always inline, there were still cases that
it did not inline! This was caused by CONFIG_PARAVIRT_GUEST, where it
would add a pointer to the native_load_idt() which made that function
to be traced.

Commit 45959ee7aa645815a ("ftrace: Do not function trace inlined functions")
only touched the 'inline' tags when CONFIG_OPMITIZE_INLINING was enabled.
PARAVIRT_GUEST shows that this was not enough and we need to also
mark always_inline with notrace as well.

ftrace: Do not function trace inlined functions

When gcc inlines a function, it does not mark it with the mcount
prologue, which in turn means that inlined functions are not traced
by the function tracer. But if CONFIG_OPTIMIZE_INLINING is set, then
gcc is allowed not to inline a function that is marked inline.

Depending on the options and the compiler, a function may or may
not be traced by the function tracer, depending on whether gcc
decides to inline a function or not. This has caused several
problems in the pass becaues gcc is not always consistent with
what it decides to inline between different gcc versions.

Some places should not be traced (like paravirt native_* functions)
and these are mostly marked as inline. When gcc decides not to
inline the function, and if that function should not be traced, then
the ftrace function tracer will suddenly break when it use to work
fine. This becomes even harder to debug when different versions of
gcc will not inline that function, making the same kernel and config
work for some gcc versions and not work for others.

By making all functions marked inline to not be traced will remove
the ambiguity that gcc adds when it comes to tracing functions marked
inline. All gcc versions will be consistent with what functions are
traced and having volatile working code will be removed.

Note, only the inline macro when CONFIG_OPTIMIZE_INLINING is set needs
to have notrace added, as the attribute __always_inline will force
the function to be inlined and then not traced.

On a tegra3 platform with Hynix eMMC we can observe that sometimes we
receive a command timeout after a transfer complete interrupt on a

Here is the output using MMC_DEBUG and ftrace.

------NOW THE REQUEST BLOCK UNTIL TIMEOUT------

We can see that when it works the multiple read blocks command stopped by
the CMD12 receive two interrupts. The first is the Transfer complete
interrupt (SDHCI_INT_RESPONSE) and just after the Block Gap Event
interrupt (SDHCI_INT_DATA_END). In this case the command is finished and
the data is finished too.

In the bad case instead of receiving SDHCI_INT_DATA_END we receive a
command timeout error (SDHCI_INT_TIMEOUT) but command was already
finished by the SDHCI_INT_RESPONSE so not more command is waiting and the
driver wait until the timeout timer end because this case is not managed.

ARM: 8429/1: disable GCC SRA optimization

While working on the 32-bit ARM port of UEFI, I noticed a strange
corruption in the kernel log. The following snprintf() statement
(in drivers/firmware/efi/efi.c:efi_md_typeattr_format())

snprintf(pos, size, "|%3s|%2s|%2s|%2s|%3s|%2s|%2s|%2s|%2s]",

was producing the following output in the log:

|    |   |   |   |    |WB|WT|WC|UC]
|    |   |   |   |    |WB|WT|WC|UC]
|    |   |   |   |    |WB|WT|WC|UC]
|RUN|   |   |   |    |WB|WT|WC|UC]*
|RUN|   |   |   |    |WB|WT|WC|UC]*
|    |   |   |   |    |WB|WT|WC|UC]
|RUN|   |   |   |    |WB|WT|WC|UC]*
|    |   |   |   |    |WB|WT|WC|UC]
|RUN|   |   |   |    |   |   |   |UC]
|RUN|   |   |   |    |   |   |   |UC]

As it turns out, this is caused by incorrect code being emitted for
the string() function in lib/vsprintf.c. The following code

if (!(spec.flags & LEFT)) {
while (len < spec.field_width--) {
if (buf < end)
*buf = ' ';
++buf;
}
}
for (i = 0; i < len; ++i) {
if (buf < end)
*buf = *s;
++buf; ++s;
}
while (len < spec.field_width--) {
if (buf < end)
*buf = ' ';
++buf;
}

when called with len == 0, triggers an issue in the GCC SRA optimization
pass (Scalar Replacement of Aggregates), which handles promotion of signed
struct members incorrectly. This is a known but as yet unresolved issue.
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65932). In this particular
case, it is causing the second while loop to be executed erroneously a
single time, causing the additional space characters to be printed.

So disable the optimization by passing -fno-ipa-sra.

For functions defined in header files we should use static inline rather
than inline, which breaks under the latest upstream gcc (which is really
gcc issue, but static inline is better suited regardless).

because gcc branched off to v5 in trunk.

Just copy the relevant bits out of include/linux/compiler-gcc4.h,

ARM: 8158/1: LLVMLinux: use static inline in ARM ftrace.h

With compilers which follow the C99 standard (like modern versions of gcc and
clang), "extern inline" does the wrong thing (emits code for an externally
linkable version of the inline function). In this case using static inline
and removing the NULL version of return_address in return_address.c does
the right thing.

apalis_t30: ixora: optionally support leds, switch, foff and wdisable

The Ixora carrier board has a few MXM3 pins repurposed as follows:

Functionality MXM3 Pin
LED4_RED 146
LED4_GREEN 162
LED5_RED 156
LED5_GREEN 152
PCIE1_WDISABLE_N 144
SW3 160
UART2_3_RS232_FOFF_N 164

This patch allows uncommenting an IXORA define in the board header file
in order to make use of those repurposed pins.

Please note that those pins are usually used for the 8-bit MMC/SD slot
aka Apalis MMC1 and the SDHCI controller/driver unfortunately changes
the output driver behaviour in a way preventing any regular GPIO use.
This patch therefore explicitly does not register the SDHCI driver on
this controller instance in the Ixora case to avoid this.

input: touchscreen: fusion: implement multitouch with slot handling

According to multi-touch-protocol.txt the kernel knows two type of
devices:
- Type A: devices which provide anonymous contacts
- Type B: devices which are capable of tracking individual contacts

The Fusion touch screen is a Type B device: The Touch ID field allows
to differentiate between 2 different fingers. This updates the driver
to properly allocate a slot for each identified contact and use the
helper functions available from the input core system.
