Patch from Bjorn Helgaas.

Lastest changes in 8250_acpi.c produce warnings about type mismatch
in printk.

Reuses the i386 cpufreq code and add an notifier to the x86-64
timer code to track frequency changes.

All previous criticism of earlier patches should be addressed:
 - it doesn't touch i386 now
 - Doesn't include the ACPI P states driver anymore following brodo's request.

Also fix a typo in the last version.

This fixes CONFIG_UID16 problems on x86-64 as discussed earlier.

CONFIG_UID16 now only selects the inclusion of kernel/uid16.c, all
conversions are triggered dynamically based on type sizes.  This allows
x86-64 to both include uid16.c for emulation purposes, but not truncate
uids to 16bit in sys_newstat. 

- Replace the old macros from linux/highuid.h with new SET_UID/SET_GID
  macros that do type checking. Based on Linus' proposal.

- Fix everybody to use them.

- Clean up some cruft in the x86-64 32bit emulation allowed by this
  (other 32bit emulations could be cleaned too, but I'm too lazy for 
  that right now) 

- Add one missing EOVERFLOW check in x86-64 32bit sys_newstat while
  I was at it.

Needs a forward declaration of struct pt_regs

Current match_token recognize "foo=" as "foo=%s". So this change the
nul string does not recognize as "%s".

If original code uses the following,

	opts->value = simple_strtoul(value, &value, 0);
	if (*value)
		return error;

It doesn't recognize negative value. So option format should use "%u".

This is just misc cleanup of fat option.

vfat doesn't recognize the msdos option. Also msdos doesn't recognize
vfat option.

And this separates fat/vfat/msdos option structures. I think this
looks more good as document.

This uses more fine granularity ->d_lock than ->dcache_lock for
->d_parent with d_move() race.

From René Scharfe <l.s.r@web.de>

there's one call to strncpy() in vfat that really should be a memcpy().
The source, msdos_name, is a space-filled char array, not a
NUL-terminated string.

The rest of the patch eliminates duplicate occurencies of the
CURRENT_TIME macro inside functions. This shrinks vfat.o by a few
bytes.

It seems that we're attempting to work out the free stack size using two
unrelated pointers for the lowest address of the stack.  Fix this to use
the correct pointer.
