the attached patch (against BK-curr) fixes a bug in the new PID allocator,
which bug can cause incorrect hashing of the PID structure which causes
infinite loops in find_pid(). [and potentially other problems.]

Patch from Rohit Seth: allow hugetlb pages to be allocated from the
highmem zone.

From Marcus Alanen <maalanen@ra.abo.fi>

Don't retake the zone lock after spilling a batch of pages into the
buddy.

Instead, just clear local variable `zone' to indicate that no lock is
held.

This is actually a common case - whenever release_pages() is called
with exactly 16 pages (truncate, page reclaim..) Marcus' patch will
save a lock and an unlock.

Also, remove some lock-avoidance heuristics in
pagevec_deactivate_inactive(): the caller has already made these
checks, and the chance of the check here actually doing anything useful
is negligible.

- Spell Jeremy's name correctly.

- Fix compile warning in raw.c

- Do a waitqueue_active() test before waking klogd in printk.

  Not only is is negligibly faster, but the wake_up() in there causes
  deadlocks when you try to print debug info out from inside scheduler
  code.

  This patch gives a delightfully obscure way of avoiding the
  deadlock: kill off klogd.

- Fix a couple of compile warnings in the mtrr code.

From Christoph Hellwig, acked by Jens.

- remove some unneeded runtime initializers.

- remove the explicit call to hd_init() - it already goes through
module_init(), so we're currently running hd_init() twice.

From Christoph Hellwig, acked by Rohit.

- fix config.in description: we know we're on i386 and we also know
that a feature can only be enabled if the hw supports it, the code
alone is not enough

- the sysctl is VM-releated, so move it from /proc/sys/kernel tp
/proc/sys/vm

- adopt to standard sysctl names

From Christoph Hellwig.

There are no lock_kernel() calls in mm/

From Hubertus Franke.

The MAP_LOCKED flag to mmap() currently does nothing.  Hubertus' patch
fixes it so that the relevant mapping is locked into memory, if the
called has CAP_IPC_LOCK.

Somebody somewhere is stomping on PF_NOWARN, and page allocation
failure warnings are coming out of the wrong places.

So change the handling of current->flags to be:

int pf_flags = current->flags;

current->flags |= PF_NOWARN;
...
current->flags = pf_flags;

which is a generally more robust approach.
