Add support for an "archheaders" target.  This target can generate
files that need to be installed for user space by "make
headers_install" or "make headers_install_all".

In order to support "make headers_install_all", it must be able to run
without the tree having to be configured first.

.. with new name.  Because nothing says "really solid kernel release"
like naming it after an extinct animal that just happened to be in the
news lately.

This avoid an extra make invocation on `prepare0'.

Commit 3d64b449

 introduced an empty file under
arch/arm/mach-zynq/board_dt.c. While this was not intended and the file
was removed from the tree by a later commit, we really should only match
junk files by known name patterns and not their size.

Replace the config_is_*() macros with a variant that allows for grepping
for usage of CONFIG_* options in the code. Usage:

  if (IS_ENABLED(CONFIG_NUMA))

or

  #if IS_ENABLED(CONFIG_NUMA)

The IS_ENABLED() macro evaluates to 1 if the argument is set (to either 'y'
or 'm'), IS_BUILTIN() tests if the option is 'y' and IS_MODULE() test if
the option is 'm'. Only boolean and tristate options are supported.

expr treats all numbers as decimals, so prepending a zero is safe. Note
that the KERNEL_VERSION() macro still takes three arguments, 3.0 has to be
written as KERNEL_VERSION(3,0,0).

Omit the second dot for releases without SUBLEVEL. If PATCHLEVEL is also
empty, only display VERSION.

.. except there are various scripts that really know that there are
three numbers, so it calls itself "3.0.0-rc1".

Hopefully by the time the final 3.0 is out, we'll have that extra zero
all figured out.

With this change, you can (and should) build with ARCH=tilepro for the
current 32-bit chips.  Building with ARCH=tile continues to work, but
we've renamed the defconfig file to tilepro_defconfig for consistency.

When mcount is called in a section that ftrace will not modify it into
a nop, we want to warn about this. But not warn about this always. Now
if the user builds the kernel with the option RECORDMCOUNT_WARN=1 then
the build will warn about mcount callers that are ignored and will just
waste execution time.

This support was partially present in the existing code (look for
"__tilegx__" ifdefs) but with this change you can build a working
kernel using the TILE-Gx toolchain and ARCH=tilegx.

Most of these files are new, generally adding a foo_64.c file
where previously there was just a foo_32.c file.

The ARCH=tilegx directive redirects to arch/tile, not arch/tilegx,
using the existing SRCARCH mechanism in the top-level Makefile.

Changes to existing files:

- <asm/bitops.h> and <asm/bitops_32.h> changed to factor the
  include of <asm-generic/bitops/non-atomic.h> in the common header.

- <asm/compat.h> and arch/tile/kernel/compat.c changed to remove
  the "const" markers I had put on compat_sys_execve() when trying
  to match some recent similar changes to the non-compat execve.
  It turns out the compat version wasn't "upgraded" to use const.

- <asm/opcode-tile_64.h> and <asm/opcode_constants_64.h> were
  previously included accidentally, with the 32-bit contents.  Now
  they have the proper 64-bit contents.

Finally, I had to hack the existing hacky drivers/input/input-compat.h
to add yet another "#ifdef" for INPUT_COMPAT_TEST (same as x86_64).

According to Documentation/Changes, the kernel should be buildable with
GNU make 3.80+.  Commit 88d7be03

 (kbuild:
Use a single clean rule for kernel and external modules) introduced the
"$(or" construct, which requires make 3.81.  This causes "make clean" to
malfunction when it is used with external modules.

Replace "$(or" with an equivalent "$(if" expression, to restore backward
compatibility.
