In order to prepare to per-arch implementations of preempt_count move
the required bits into an asm-generic header and use this for all
archs.

In order to promote interoperability between userspace tracers and ftrace,
add a trace_clock that reports raw TSC values which will then be recorded
in the ring buffer. Userspace tracers that also record TSCs are then on
exactly the same time base as the kernel and events can be unambiguously
interlaced.

Tested: Enabled a tracepoint and the "tsc" trace_clock and saw very large
timestamp values.

v2:
Move arch-specific bits out of generic code.
v3:
Rename "x86-tsc", cleanups
v7:
Generic arch bits in Kbuild.

Ease the deployment of clkdev by providing a default asm/clkdev.h for
use if the arch does not have an include/asm/clkdev.h.

Due to limitations in Kbuild we manually add clkdev.h to all
architectures that don't have one rather than having the header appear
by default.

unifdef-y and header-y have same semantic, so drop unifdef-y

Add swab.h to kbuild.asm and remove the individual entries from
each arch, mark as unifdef as some arches have some kernel-only
bits inside.

Sam Ravnborg did the build-test that the direct header file move works,
I'm just committing it.

This is a pure move:

	mkdir arch/alpha/include
	git mv include/asm-alpha arch/alpha/include/asm

with no other changes.

Alpha currently fails 'make headers_check' in the 2.6.18-rc kernels.  This
patch fixes it, by moving the existing #ifdef __KERNEL__ in asm/page.h so that
it covers everything that userspace shouldn't so, and by adding asm/compiler.h
to the list of exported files so that its use within asm/byteorder.h is
successful.

[ Note that at least with GCC 4, <linux/compiler.h> doesn't do the forced
  inlining about which there are nasty comments (and a workaround) in
  <asm/compiler.h>, unless you set CONFIG_FORCED_INLINING.  Rather than keep
  the mess you have in <asm/compiler.h> you could perhaps just make sure
  CONFIG_FORCED_INLINING=n is also honoured with GCC3, and make sure it cannot
  be set for Alpha? ]
