The dynamic add path for PCI Host Bridges can fail to configure children
adapters under P5IOC controllers.  It fails to properly fixup bus/device
resources, and it fails to properly enable EEH.  Both of these steps
need to occur before any children devices are enabled in
pci_bus_add_devices().

The recent changes to keep gettimeofday in sync with xtime had the side
effect that it was occasionally possible for the time reported by
gettimeofday to go back by a microsecond.  There were two reasons:
(1) when we recalculated the offsets used by gettimeofday every 2^31
timebase ticks, we lost an accumulated fractional microsecond, and
(2) because the update is done some time after the notional start of
jiffy, if ntp is slowing the clock, it is possible to see time go backwards
when the timebase factor gets reduced.

This fixes it by (a) slowing the gettimeofday clock by about 1us in
2^31 timebase ticks (a factor of less than 1 in 3.7 million), and (b)
adjusting the timebase offsets in the rare case that the gettimeofday
result could possibly go backwards (i.e. when ntp is slowing the clock
and the timer interrupt is late).  In this case the adjustment will
reduce to zero eventually because of (a).

* master.kernel.org:/home/rmk/linux-2.6-arm:
  [ARM] 3362/1: [cleanup] - duplicate decleration of mem_fclk_21285
  [ARM] 3365/1: [cleanup] header for compat.c exported functions
  [ARM] 3364/1: [cleanup] warning fix - definitions for enable_hlt and disable_hlt

  [ARM] 3358/1: [S3C2410] add missing SPI DMA resources
  [ARM] 3357/1: enable frontlight on collie
  [ARM] Fix "thead" typo

This fixes not one, but _two_, silly (but admittedly hard to hit) bugs
in the ext2 filesystem "readdir()" function.  It also cleans up the code
to avoid the unnecessary goto mess.

The bugs were related to re-valiating the f_pos value after somebody had
either done an "lseek()" on the directory to an invalid offset, or when
the offset had become invalid due to a file being unlinked in the
directory.  The code would not only set the f_version too eagerly, it
would also not update f_pos appropriately for when the offset fixup took
place.

When that happened, we'd occasionally subsequently fail the readdir()
even when we shouldn't (no real harm done, but an ugly printk, and
obviously you would end up not necessarily seeing all entries).

Thanks to Masoud Sharbiani <masouds@google.com> who noticed the problem
and had a test-case for it, and also fixed up a thinko in the first

page migration currently simply retries a couple of times if try_to_unmap()
fails without inspecting the return code.

However, SWAP_FAIL indicates that the page is in a vma that has the
VM_LOCKED flag set (if ignore_refs ==1).  We can check for that return code
and avoid retrying the migration.

migrate_page_remove_references() now needs to return a reason why the
failure occured.  So switch migrate_page_remove_references to use -Exx

* git://oss.sgi.com:8090/oss/git/rc-fixes:
  Fix a direct I/O locking issue revealed by the new mutex code.

Affects only XFS (i.e. DIO_OWN_LOCKING case) - currently it is
not possible to get i_mutex locking correct when using DIO_OWN
direct I/O locking in a filesystem due to indeterminism in the
possible return code/lock/unlock combinations.  This can cause
a direct read to attempt a double i_mutex unlock inside XFS.

We're now ensuring __blockdev_direct_IO always exits with the
inode i_mutex (still) held for a direct reader.

Tested with the three different locking modes (via direct block
device access, ext3 and XFS) - both reading and writing; cannot
find any regressions resulting from this change, and it clearly
fixes the mutex_unlock warning originally reported here:

- Disable the EDAC sysfs code.  The sysfs interface that EDAC presents to
  user space needs more thought, and is likely to change substantially.
  Therefore disable it for now so users don't start depending on it in its

- Disable the default behavior of calling panic() when an uncorrectible
  error is detected (since for now, there is no sysfs interface that allows
  the user to configure this behavior).
