[PATCH] Avoid console spam with ext3 aborted journal.

Avoid console spam with ext3 aborted journal.

ext3 usually reports error conditions that it detects in its environment.
But when its journal gets aborted due to such errors, it can sometimes
continue to report that condition forever, spamming the console to such
an extent that the initial first cause of the journal abort can be lost.

When the journal aborts, we put the filesystem into readonly mode.  Most
subsequent filesystem operations will get rejected immediately by checks
for MS_RDONLY either in the filesystem or in the VFS.  But some paths do
not have such checks --- for example, if we continue to write to a file
handle that was opened before the fs went readonly.  (We only check for
the ROFS condition when the file is first opened.)  In these cases, we
can continue to generate log errors similar to

EXT3-fs error (device $DEV) in start_transaction: Journal has aborted

for each subsequent write.

There is really no point in generating these errors after the initial
error has been fully reported.  Specifically, if we're starting a
completely new filesystem operation, and the filesystem is *already*
readonly (ie. the ext3 layer has already detected and handled the
underlying jbd abort), and we see an EROFS error, then there is simply
no point in reporting it again.

[PATCH] Fix filp being passed through raw ioctl handler

Don't pass meaningless file handles to block device ioctls.

The recent raw IO ioctl-passthrough fix started passing the raw file
handle into the block device ioctl handler.  That's unlikely to be
useful, as the file handle is actually open on a character-mode raw
device, not a block device, so dereferencing it is not going to yield
useful results to a block device ioctl handler.

Previously we just passed NULL; also not a value that can usefully
be dereferenced, but at least if it does happen, we'll oops instead of
silently pretending that the file is a block device, so NULL is the more
defensive option here.  This patch reverts to that behaviour.

I have finally done some work to update the CompactPCI hotplug driver to
fix some of the outstanding issues in 2.6:
- Added adapter and latch status ops so that those files will get created
  by the current PCI hotplug core.  This used to not be required, but
  seems to be now after some of the sysfs rework in the core.
- Replaced slot list spinlock with a r/w semaphore to avoid any potential
  issues with sleeping.  This quiets all of the runtime warnings.
- Reworked interrupt driven hot extraction handling to remove need for a
  polling operator for ENUM# status.  There are a lot of boards that only
  have an interrupt driven by ENUM#, so this lowers the bar to entry.
- Replaced pci_visit_dev usage with better use of the PCI core functions.
  The new code is functionally equivalent to the previous code, but the
  use of pci_enable_device on insert needs to be investigated further, as
