compile.h is created super-late in the build.  But proc_misc.c want to include
it, and it's generally not sane to have a header file in include/linux be
created at the end of the build: it's either not present or, worse, wrong for
most of the build.

So the patch arranges for compile.h to be built at the start of the build
process.  It also consolidates the compile.h rules with those for version.h
and utsname.h, so they all get built together.

I hope.  My chances of having got this right are about 2%.

It has caused more problems than it ever really solved, and is
apparently not getting cleaned up and fixed.  We can put it back when
it's stable and isn't likely to make warning or bug events worse.

The previous checkstack fix for UML, which needs to use the host's tools,
was wrong in the crossbuilding case.  It would use the build host's, rather
than the target's, toolchain.

This patch removes the old fix and adds an explicit special case for UML,
leaving everyone else alone.

While `make -rR is now default' commit should fix this, actually, it was just

Ok, things are clearly starting to calm down.. Finally.

Not halloween. Not scary. Just a regular -rc release.

This changes the dwarf2 unwinder to do a binary search for CIEs
instead of a linear work. The linker is unfortunately not
able to build a proper lookup table at link time, instead it creates
one at runtime as soon as the bootmem allocator is usable (so you'll continue
using the linear lookup for the first [hopefully] few calls).
The code should be ready to utilize a build-time created table once
a fixed linker becomes available.

Merge window closed..

Not all architectures have a file named 'defconfig' (e.g.  powerpc).
However the make TAGS and make tags targets search such files for tags,
causing an error message when they don't exist.  This patch addresses the
problem by instructing xargs not to run the tags program if there are no
matching files.

         (2) - due to target missing
         (3) - due to: file1.h file2.h

         (5) - due to missing .cmd file
         (6) - due to target not in $(targets)
(1) We always build PHONY targets
(2) No target, so we better build it
(3) Prerequisite is newer than target
(4) The command line stored in the file named dir/.target.cmd
    differed from actual command line. This happens when compiler
    options changes
(5) No dir/.target.cmd file (used to store command line)
(6) No dir/.target.cmd file and target not listed in $(targets)
    This is a good hint that there is a bug in the kbuild file

`make headers_check' wants to go and write stuff in /lib/modules, which
requires root, whic is unfortunate.

In fact, there's no _particular_ reason for headers_install to put it there
either -- it can go into a subdirectory of the build tree in both cases.
It's not intended to go directly into /usr/include, which is why we didn't
put it there -- and we certainly don't want people screwing around with
symlinking to it.  It's for distributors to take away and do stuff with, so
leaving it in $(objtree) is fine, even in the headers_install case.

I picked $(objtree)/usr/include but I have no _particular_ preference
for that; it just seemed reasonable.
