This reverts commit c8fdd247.

It turns out the kernel was correct, and the gcc complaint was a gcc
bug.  The preferred stack boundary is expressed not in bytes, but in the
the log2() of the preferred boundary, so "-mpreferred-stack-boundary=2"
is in fact exactly what we want, but a gcc that is compiled for x86-64
will consider it an error (because the 64-bit calling sequence says that
the stack should be 16-byte aligned) even if we are then using "-m32" to
generate 32-bit code.

.. close the merge window

Most system calls seems to get added to i386 first. This patch
automatically generates a warning for any new system call which is
implemented on i386 but not the architecture currently being compiled.
On PowerPC at the moment, for example, it results in these warnings:
init/missing_syscalls.h:935:3: warning: #warning syscall sync_file_range not implemented
init/missing_syscalls.h:947:3: warning: #warning syscall getcpu not implemented
init/missing_syscalls.h:950:3: warning: #warning syscall epoll_pwait not implemented

The file scripts/checksyscalls.sh list a number of legacy system calls
that are ignored because they only makes sense on i386 systems.

Move tags extracted from the ARCH and include/ sub-trees ahead of
those from device drivers, so that the former will appear first
during searches.

Saves user time during interactive searches for certain patterns
that happen to find unwanted matches in driver files.

Example in emacs:
	 "M-x find-tag PAGE_SIZE"
	 "M-1 M-." (repeated until definition from asm-i386/page.h appears)

The kernel only supports gcc 3.2+ now so it doesn't make sense
anymore to explicitely check for options this compiler version
already has.

This actually fixes a bug. The -mprefered-stack-boundary check
never worked because gcc rightly complains

  CC      arch/i386/kernel/asm-offsets.s
cc1: -mpreferred-stack-boundary=2 is not between 4 and 12

We just never saw the error because of cc-options.
I changed it to 4 to actually work.

Tested by compiling i386 and x86-64 defconfig with gcc 3.2.

Should speed up the build time a tiny bit and improve
stack usage on i386 slightly.

Too many changes for comfort since -rc1.  Some missed merges, and some
just annoyingly big fixes since.  This is not how an -rc2 should look.
Need to really calm things down!

Add new headers_check_all target for checking all arches in one go.

Useful for distros (and people with too much time on their hands) that support
a ton of architectures, headers_check_all is to headers_check as
headers_install_all is to headers_install

`make help' in the build tree doesn't show the help texts about the
`headers_install' and `headers_check' targets because it looks for

...because it's always a good idea to cut a release *before* you go out

Remember kids: "Don't Drink and Release!"

include/linux/utsrelease.h and include/linux/version.h aren't removed any
more by mrproper in kernel 2.6.20-rc2.  The patch below fixes this.

The definition of MRPROPER_FILES looks weird: generated-headers looks like
a misspelling of generated_headers, but that one is a Makefile target, not
a variable or a file, so I don't see how including it in MRPROPER_FILES
could have any effect.

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

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,
