  condition, we test the preemption count in preempt_schedule(). This reduces the icache
  footprint and the overhead of preemption.

- plus optimize the irq-path preemption check a bit.

this is a fragile piece of the ptrace code, the code relies on a single wakeup coming from the parent.
This fix is necessery after the preempt_schedule() cleanups, it unbreaks 'strace strace ...'.

fixes a preemption race that was introduced by my removal of PREEMPT_ACTIVE.

- the PREEMPT_ACTIVE trick is not needed

- schedule() should check for need_resched, we might miss a
  reschedule otherwise.

the cleanup also fixes the bug. The only reason why i kept
preempt_schedule() was to fix up p->state to TASK_RUNNING,
to make it possible to preempt from places that mark the
task TASK_UNINTERRUPTIBLE before adding the task to a waitqueue,
and thus a preemption in that small window could cause the
task to be removed from the runqueue erroneously.

	BKL shifted into all instances of ->truncate().  Callers updated.

	OK, here comes: ->lookup() had lost BKL, all in-tree instances of
->lookup() converted.

	I'm adding Documentation/filesystems/porting - with the list of
API changes since 2.4.  Are you OK with that format?

(and yes, this sucker is *post*-compile ;-)

Now that the input core changes have made it into 2.5 I can finally
update the USB input drivers to their latest versions.

Here is a patch that does that.

In detail:

	HID driver:
		Fix a bug in descriptor parsing (array/variable),
			namely visible with Logitech new joysticks and mice
		Fix bugs in logical/physical min/max parsing
		Fix bugs in exponent parsing
		Remove workaround for low-speed devices with >8 byte
			reports, fix this in a correct way (bigger irq
			request)
		Untangle some code (fetc_item())
		Implement asynchronous input/output/feature report
			reading and writing
		Implement (hopefully) proper locking in the above
		Implement support for devices with an output endpoint
		Add some support functions for force feedback support
			currently in development
		Add entries to the debug dump code, including FF and
			exponents
		Add more mappings into the hid-input interface
		Cleanups here and there

	usbkbd driver:

		Make LED URBS use GFP_ATOMIC, they'll be called from a
			completion handler
		Remove dependency on hid.h

	usbmouse driver:

		Just conversion to the new input core, minor cleanups

	wacom driver:

		Just conversion to the new input core.

this patch somehow didn't get applied to 2.5.4
so i resend it.  It is pretty harmless - only
adds 3 more devices and 2 vendor ids into pegasus.h :-)

mmap currently sets errno to EINVAL when it should be ENOMEM.
SUS/POSIX states that ENOMEM should be returned when:

"MAP_FIXED was specified, and the range [addr, addr + len) exceeds
that allowed for the address space of a process; or if MAP_FIXED was
not specified and there is insufficient room in the address space to
effect the mapping."

The following patch (against 2.4.17) fixes this behaviour:

* fs/ncpfs/inode.c: Return reasonable error codes instead of universal
     -EINVAL. Remove printk() as reasonable code is returned.
     Set maximum file size limit on ncpfs to 4GB-1.

* fs/ncpfs/sock.c: Return correct error code when send() fails.

* zisofs_cleanup cannot be __exit, as it is invoked from __init
  section when register_filesystem() fails.
