This contains the following changes:

a) changes from Intel to support the new microcode data format
   (backward compatible of course)

b) changes from me to remove the no longer needed features of the driver,
   namely we don't need to keep a copy of applied microcode in kernel
   memory.

   This feature was hardly useful in the days of regular devfs
   /dev/cpu/microcode file and now it is completely useless so I removed
   it (after taking into account all the feedback on linux-kernel I
   received since the announcement of the intention to do this)

These are rather critical because otherwise we can't really say Linux
fully supports the very latest Intel cpus (which require microcode in
the new format).

Plus with a little codeshuffling, we can do away with the
prototypes.

There's three drivers in the tree that workaround the suboptimal
devfs name choice of the misc device layer (/dev/misc/<foo>) using
devfs_mk_symlink.    Switch them to set miscdev.devfs_name instead
to get the right name from the very beginning.

register a /dev/cpu/microcode symlink instead of a regular file
with the same name - regular file support is gone in devfs.

It's the _device_ filesystem, so regular files are grossly misplaced
here.  Fortauntely only one driver actually tries to use it (microcode)
and it's works fine with  a regular miscdevice as well.

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

Based on a patch from Dave Jones.

It converts a large number of instances of:

	smp_call_function(foo);
	foo();

into

	on_each_cpu(foo);

and in doing so fixes up the preempt-unsafeness of the first version.

From:  Chris Wilson <chris@qwirx.com>

  If the call to devfs_register() fails, then the driver does not deregister
  its misc device before returning an error. This should fix it.

The old form of designated initializers are obsolete: we need to
replace them with the ISO C forms before 2.6.  Gcc has always supported
both forms anyway.

This patch removes the concept of "logical" CPU numbers, in
preparation for CPU hotplugging.

This removes <linux/mm.h> from <linux/vmalloc.h>.

This then goes and fixes all of the files (x86 and PPC) which relied on
implicit includes which don't happen anymore.  This also takes
<linux/kdev_t.h> out of fs/mpage.c and puts it into include/linux/bio.h
where it belongs since <linux/bio.h> references 'kdev_t' directly.

A quick summary of the of the added includes:
arch/i386/kernel/microcode.c: needs extern for num_physpages, in linux/mm.h
include/linux/spinlock.h: local_irq* is defined in <asm/system.h> but
this was never directly included.

This patch cleans up the remaining direct tests against x86_capability.
      It moves the cpu_has_* macros to the more appropriate
cpufeature.h.  It also introduces the cpu_has() macro to test features
for individual cpus.

Fix some set_bit() warnings.

The obvious patch to fix compiler warning when compiled with RH gcc 2.96
(and probably others too).
