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.

mn10300 has a header (in its include/asm directory) that is a thin
wrapper around asm-generic/ipc.h. This wrapper is useless, since that
header doesn't exist. It is also unused (no file includes asm/ipc.h).

hexagon and tile generate similar headers at build time (using a
generic-y entry in include/asm/Kbuild). These generated headers are
useless and unused too.

Remove this header and these generic-y entries.

frv and xtensa both have a header (in their include/asm directories)
that are thin wrappers around asm-generic/cpumask.h. These wrappers are
useless, since that header doesn't exist. They are also unused (all
files including asm/cpumask.h are x86 specific).

hexagon and openrisc generate similar headers at build time (using a
generic-y entry in include/asm/Kbuild). These generated headers are
useless and unused too.

Remove these headers and generic-y entries.

Move all header files for xtensa to arch/xtensa/include and platform and
variant header files to the appropriate arch/xtensa/platforms/ and
arch/xtensa/variants/ directories.

Moving the files gets also rid of all uses of symlinks in the Makefile.

This has been completed already for the majority of the architectures
and xtensa is one out of six missing.

These include nothing more than the basic set of files listed in
asm-generic/Kbuild.asm. Any extra arch-specific files will need to be
added.
