This adds m68k defines for __kernel_timer_t and __kernel_clockid_t.  The
reset signal changes means these are now needed.

This creates a sturcture to mirror the m68knommu/ColdFire CPU timer
hardware.  This is a much cleaner approach to accessing the timer
registers than the previous set of register address defines.

This modifies the m68knommu siginfo include file to use
asm-generic/siginfo.h instead of the asm-m68k/siginfo.h.

The asm-generic/siginfo.h is more appropriate here, and
the m68k is out of date.

This includes asm/unistd.h in the system call table setup code for
m68knommu.  It needs the local NR_syscalls define.  linux/unistd.h is
not assembler clean, so it must be asm/unistd.h.

The patch below does the following:
- remove #if'd kernel 2.2 code
- changes one MIN to min

Someone nuked the 2nd arg in 2.5.62, but didn't fix up
all the callers. Lazy.

Patch from Andries.Brouwer@cwi.nl

A patch for genhd.c:

- removed outdated comments
- removed MAX_BLKDEV

In genhd.c the variable MAX_BLKDEV was only the size of a hash
table, so I made it MAX_PROBE_HASH. It can be 1, or 23, or 256, or
whatever one wants.

Note that the current setup requires that every device number
in a given range is mapped by dev_to_index() to the same index
in the hash table, so this routine will have to be adapted in
case one wants to register multimajor ranges.

Discussion is possible about whether struct blk_probe needs
a dev_t or a kdev_t, but I left things this time.

If a range can end at precisely the end of [k]dev_t space,
the old code was wrong since (p->dev + p->range) would be 0.
That is why "p->dev + p->range <= dev" was replaced by
"p->dev + p->range - 1 < dev".

This is a forward-port of a 2.4 change from Stephen.  The (old) 2.5 code is
forcing a commit on every write by artificially dirtying the inode.

But generic_file_aio_write() has called generic_osync_inode() for us, which
has synced the file data.  There is no need to force the extra commit.

Patch from Thomas Schlichter <schlicht@uni-mannheim.de>

Adds some missing global_flush_tlb() calls, which are requried after a call
to change_page_attr().

Patch from Rik van Riel <riel@imladris.surriel.com>

If a process cannot exit because it's stuck in eg.  a driver, it doesn't make
sense to have the OOM killer kill it repeatedly; that could lead to a hung
system.

Instead, kill another process if the first process we tried to kill hasn't
made any move to exit within 5 seconds.  This way we have a much better
chance of recovering the system.

Patch from "Martin J. Bligh" <mbligh@aracnet.com>

Fixes up the logic and code which is used to suppress the IRQ balancing code.

We now just have a single boolean, "irqbalance_disabled".  The initial value
comes from the per-platform "NO_BALANCE_IRQ" constant.

If the platform defaults to "on", users can override this with the
"noirqbalance" kernel boot option.

Patch from Alex Tomas <bzzz@tmi.comex.ru>

Fixes a couple of memory leaks in the htree code.

Patch from John Levon <levon@movementarian.org>

Looked like this condition was previously always false ...

Patch from Hugh Dickins <hugh@veritas.com>

When prune_icache coincides with unmounting, invalidate_inodes notices
the inode it's working on as busy but doesn't wait: Self-destruct in 5
seconds message, and later iput oopses on freed super_block.

Neither end is a fast path, so the patch just adds iprune_sem for exclusion.

The semaphore is held across dispose_list so that
dispose_list->clear_inode->destroy_inode cannot reference a destroyed
superblock.

Patch from Rick Lindsley <ricklind@us.ibm.com>

Fixes a couple of odd cases in which disk requests were not being accounted
for.

This check is not needed - the PMD is known to be present.

Patch from Maneesh Soni <maneesh@in.ibm.com>

Turns out that sysfs is doing dget() on a zero-ref dentry.  That's a bug, but
dcache is no longer detecting it.

The check was removed because with lockless d_lookup, there can be cases when
d_lookup and dput are going on concurrently, If d_lookup happens earlier then
it may do dget() on a dentry for which dput() has decremented the ref count
to zero.  This race is handled by taking the per dentry lock and checking the
DCACHE_UNHASHED flag.

The patch open-codes that part of d_lookup(), and restores the BUG check in
dget().
