Instead of doing a "int 0x80" instruction for system calls,
user space can do a "call 0xfffff000" which will do the right
thing regardless of what kind of system call support the CPU
has.

The linear target was getting the start sector wrong when doing a
dm_get_device(). [Kevin Corry]

The block layer does not honour bio->bi_size when issuing io, instead
it performs io to the complete bvecs.  This means we have to change
the bio splitting code slightly.

Given a bio we repeatedly apply one of the following three operations
until there is no more io left in the bio:

1) The remaining io does not cross an io/target boundary, so just
   create a clone and issue all of the io.

2) There are some bvecs at the start of the bio that are not split by
   a target boundary.  Create a clone for these bvecs only.

3) The first bvec needs splitting, use bio_alloc() to create *two*
   bios, one for the first half of the bvec, the other for the second
   half.  A bvec can never contain more than one boundary.

o  If there's an error you still need to call bio_endio with bio->bi_size
   as the 'done' param.

o  Simplify clone_endio.

Remove verbose debug message 'Splitting page'.

Remove some paranoia in highmem.c

Some fields in the duplicated bio weren't being set up properly in
__split_page(). [Kevin Corry]

md->pending was being incremented for each clone rather than just
once. [Kevin Corry]

dec_pending(): only bother spin locking if io->error is going to be
updated. [Kevin Corry]

Add a blk_run_queues() call to encourage pending io to flush
when we're doing a dm_suspend().

dm_suspend(): Stop holding the read lock around the while loop that
waits for pending io to complete.

queue_io() was checking the DMF_SUSPENDED flag rather than the new
DMF_BLOCK_IO flag.  This meant suspend could deadlock under load.

Give each device its own io mempool to avoid a potential
deadlock with stacked devices.  [HM + EJT]

There's a bug in the dm-stripe.c constructor failing top check if enough
destinations are handed in. [Heinz Mauelshagen]

minor change for dm-stripe.c. Tests for correct chunksize before it allocates
the stripe context. [Heinz Mauelshagen]

check_device_area was comparing the bytes with sectors.
[Stefan Lauterbach]

No need to validate the parameters if we are doing a
REMOVE_ALL command.

Return -ENOTBLK if lookup_device() finds the inode, but it
is not a block device. [Cristoph Hellwig]

An error value was not being checked correctly in open_dev().
[Kevin Corry]

Four constants:
   DM_DIR,
   DM_MAX_TYPE_NAME,
   DM_NAME_LEN,
   DM_UUID_LEN

Were being declared in device-mapper.h, these are all specific to
the ioctl interface, so they've been moved to dm-ioctl.h.  Nobody
in userland should ever include <linux/device-mapper.h> so remove
ifdef __KERNEL guards.

The writepage-removal patch broke filesystems which do not want to
support writeable mappings.

Fix that up by making those filesystems point their mmap vector at the
new generic_file_readonly_mmap().

This patch addes the new restart_block field support to m68knommu
thread_info.h.

This patch adds a definition for TASK_UNMAPPED_BASE in m68knommu
process.h.  Recent changes need a definition for this, although its
value is unsed for nommu targets.

The patch include cache.h in m68knommu hardirq.h.

Cleans up compile problems, and make its consistent with
all other architecture hardirq.h files.

This changes m68knommu current.h to include the linux/thread_info.h
instead of asm/thread_info.h.  This is needed to get the restart_block
definition from linux/thread_info.h first.

This fixes the broken ELF_CORE_COPY_REGS macro for m68knommu arch.  It
is missing a ";" after the pr_reg[16] setting, and attempts to set the
non-existant a2 field.

This removes use of the depricated sys_security system call entry for
the m68knommu architectures.

This adds spinlocks around calls to generic kernel signal routine calls.

This adds the missing argument to do_fork() calls in m68knommu arch
process.c

This fixes the use kstat_cpu in m68knommu arch ints.c Replcae obsolete
use of kstat.irqs.

This little patch changes the way button release events are reported
by the sonypi driver to the application: previously, separate
release events were detected for each button. However, many buttons
(example: the jogdial, the capture button, the back button etc) share
the same release event.

The attached patch propagates a single 'ANYBUTTON_RELEASED' event
to the userspace, leaving all state machine intelligence to the
application.

Kunihiko IMAI should be credited for his ideas and tests.

The enclosed patch fix compile problems and adds all the diffs which
were still missing from 2.5.51.

This covers a lot of ground in the Linux1394 SVN tree.  I haven't had
time to keep in sync with you in a more granular way, so here's a
bohemoth patch.  However, consider it well tested.
