VMALLOC_START and VMALLOC_OFFSET are common between all ARM
machine classes. Move them into include/asm-arm/pgtable.h,
but allow a machine class to override them if required.

This patch is for -mm only. It should probably be included in git-audit,
and should be forwarded to Linus iff git-audit is.
It updates the audit-syscall-{entry,exit} calls to current -mm.

Modify xtSearch so that it returns the next allocated block when the
requested block is unmapped. This can be used to make sure we don't
create a new extent that overlaps the next one.

This patch adds jfs_syncpt, which calls lmLogSync to write sync points
to the journal both in jfs_sync_fs and when sync barrier processing
completes.
lmLogSync accomplishes two things: 1) it pushes logged-but-dirty
metadata pages to disk, and 2) it writes a sync record to the journal
so that jfs_fsck doesn't need to replay more transactions than is
necessary.

JFS was creating a new IAG (inode aggregate group) in one address
space, and afterwards, accessing it from another. This could lead to
complications when cache pages contain more than one page of jfs
metadata. This patch causes the IAG to be initialized in the same
address space that it is subsequently accessed with.
This also elimitates an I/O, but IAG's aren't created too often.

Use an inline pxd list rather than an xad list in the xadlock.
When the number of extents being modified can fit with the xadlock,
a transaction can be committed asynchronously. Using a list of
pxd's instead of xad's allows us to fit 4 extents, rather than 2.

The cpufreq core patch I sent earlier got only half-applied. I added a
flag to let the low level driver disable an annoying warning on
suspend/resume that is normal on ppc, but the "resume" part of it wasn't
applied.
This just adds back that missing bit. The original patch also reworked
the resume() function to avoid nesting too many if () statements along
the way I did the suspend() one, but I didn't include that in the patch
below.

The clock spreading disable/enable code was called to late/early during
the suspend/resume code on some laptops and would trigger a
might_sleep() warning due to the down() call in the low level i2c code.
This fixes it by calling those functions earlier/later when interrupts
are still enabled.

A typo in the machine table incorrectly mark the 101 PowerBook as
needing explicit callback from the video driver to enable sleep mode. I
did not implement that mecanism for chipsest older than r128, so we need
to mark this machine as always beeing able to sleep for now.

We are experiencing a problem when flushing the CPU caches before sleep
on some laptop models using the 750FX CPU rev 1.X. While I haven't been
able to figure out a proper explanation for what's going on, I do have a
workaround that seem to work reliably and allows those machine to sleep
and wakeup properly again.
I'll re-update that code if/when I ever find exactly what is happening
with those CPU revisions.

scsi_dispatch_cmd currently calls scsi_done when the device is in the
SDEV_DEL state, but at this point the command has not had a timer added
to it (this is done a couple lines down) so scsi_done just returns and
the command is lost. The attached patch made against 2.6.12-rc3 calls
__scsi_done in this case so the comamnd will be returned upwards.
