drivers/md/xor.c needs kernel_fpu_begin() for the mmx checksumming functions.
 So export that to GPL modules.

use `unsigned long' for a jiffies-holding type.

use-after-free races have been seen due to the workqueue timer in the tty
structure going off after the tty was freed.

Fix that up by using cancel_scheduled_work() and flush_scheduled_work().

The workqueue code currently has a notion of a per-cpu queue being "busy".
flush_scheduled_work()'s responsibility is to wait for a queue to be not busy.

Problem is, flush_scheduled_work() can easily hang up.

- The workqueue is deemed "busy" when there are pending delayed
  (timer-based) works.  But if someone repeatedly schedules new delayed work
  in the callback, the queue will never fall idle, and flush_scheduled_work()
  will not terminate.

- If someone reschedules work (not delayed work) in the work function, that
  too will cause the queue to never go idle, and flush_scheduled_work() will
  not terminate.

So what this patch does is:

- Create a new "cancel_delayed_work()" which will try to kill off any
  timer-based delayed works.

- Change flush_scheduled_work() so that it is immune to people re-adding
  work in the work callout handler.

  We can do this by recognising that the caller does *not* want to wait
  until the workqueue is "empty".  The caller merely wants to wait until all
  works which were pending at the time flush_scheduled_work() was called have
  completed.

  The patch uses a couple of sequence numbers for that.

So now, if someone wants to reliably remove delayed work they should do:


	/*
	 * Make sure that my work-callback will no longer schedule new work
	 */
	my_driver_is_shutting_down = 1;

	/*
	 * Kill off any pending delayed work
	 */
	cancel_delayed_work(&my_work);

	/*
	 * OK, there will be no new works scheduled.  But there may be one
	 * currently queued or in progress.  So wait for that to complete.
	 */
	flush_scheduled_work();


The patch also changes the flush_workqueue() sleep to be uninterruptible.
We cannot legally bale out if a signal is delivered anyway.

- oprofile is currently only profiling one sibling.  Fix that with
  appropriate register settings.

- fix an oops which could occur if the userspace driver were to request a
  non-existent resource.

- in NMI handler counter_config[i].event is accessible from user space so
  user can change the event during profiling by echo xxx >
  /dev/oprofile/event

- event mask was wrong, the bit field is 6 bits length not 5, events
  SSE_INPUT_ASSIST and X87_SIMD_MOVES_UOP was affected by masking high bit of
  event number.

A few places were missing the rwlock->spinlock conversion.

macro argument, so that portability issues will be found in
a timely manner.

This fixes oopses when it and the hid core are compiled into the kernel.

Amiga Gayle IDE fixes: Set hwif->mmio to 2 to prevent the generic IDE core from
messing with our resources

Amiga keyboard: fix default keyboard mappings:
  - Map the parentheses keys on the numeric keypad to KPLEFTPAREN and

  - Map the Help key to HELP (was: F11)
  - Map the Amiga keys to LEFTMETA and RIGHTMETA (was: RESERVED)

IDE: Print IRQ number in decimal on m68k

unmap_vmas() eventually calls tlb_start_vma(), where most architectures
flush caches as necessary.  The flush here seems to make the
flush_cache_range() in zap_page_range() redundant, and therefore can be
removed.

I managed to add a bug to the local APIC NMI watchdog's
resume procedure in the driver model conversion for 2.5.67.
The problem is that the resume procedure simply calls the
enable procedure. If the NMI watchdog has been disabled by
another driver (like oprofile or perfctr), then the NMI
watchdog will incorrectly be re-enabled.

I discovered this when updating the perfctr driver for 2.5.67
and seeing unexpected NMIs after a resume from apm --suspend.

We can fix this by unregistering the NMI watchdog from the
driver model when disabling it (like the code did before the
driver model changes), or by remembering the previous state
at suspend and checking it at resume. The patch below uses
the second, simpler, approach. Tested, please apply.
