unifdef utility is fast enough to warrant that we always
run the scripts through unifdef.
This patch runs all headers listed with header-y and unifdef-y
through unifdef.
Next step is to drop unifdef-y in all Kbuild files and
that can now be done in smaller steps.

The sed expression used at the moment in scripts/Makefile.headersinst
relies on the (handy) GNU extension where you can escape ERE's in an
otherwise BRE without using the GNU -r option. The following patch
replaces this "\+" usage with a functionally equivalent POSIX BRE compliant
"\{1,\}". Tested with `make headers_install` against blackfin/x86_64/i386
targets.
Stupid whiny OS X users and their crappy sed ;)

A bug in headers_install for ARCH=x86_64 yields an asm/ directory full of
files all of which are using the same #ifdef guard, "__ASM_STUB_" with no
postfix. So the second and later asm files #included in the same C file
(often through standard headers like ioctl.h) yields no symbols.
Strangeness with the Ubuntu 'tell me if I support something that's not
explcitly mentioned in POSIX, and I'll strip it out' shell, I believe.
We don't need the 'export' but we do need a semicolon at the end of the
FNAME line:

This should make it stop immediately after printing the _helpful_ error
message, rather than continuing to spit out many pages more of 'CHECK
include/linux/foo.h' before eventually coming to a halt with something
less obvious.
Now I get this...
CHECK include/linux/smb_fs.h
/shiny/git/linux-2.6/usr/include/linux/smb_fs.h requires linux/jiffies.h, which does not exist in exported headers
make[2]: *** [/shiny/git/linux-2.6/usr/include/linux/.check.smb_fs.h] Error 1

The current filename->define translation does not scrub dashes so when
creating stub defines for like asm-x86_64/ptrace-abi.h, we get: #define
__ASM_STUB_PTRACE-ABI_H
gcc just hates that sort of thing :)

Use dependencies for 'make headers_install'.
[S390] Unexport <asm/z90crypt.h>, export <asm/zcrypt.h> in its place.
Remove dead netfilter_logging.h from include/linux/Kbuild
Remove offsetof() from user-visible <linux/stddef.h>
Clean up exported headers on CRIS
Fix v850 exported headers
Don't advertise (or allow) headers_{install,check} where inappropriate.
Remove UML header export
Remove ARM26 header export.
Fix H8300 exported headers.
Fix m68knommu exported headers
Fix exported headers for SPARC, SPARC64
Fix 'make headers_check' on m32r
Fix 'make headers_check' on sh64
Fix 'make headers_check' on sh
[HEADERS] Fix ARM 'make headers_check'
Initial pass of manual conflict resolution in top-level Makefile over
conflicting build rule and headers_install changes.
Re-export header files only if either they or their controlling Kbuild
file has actually changed. Also allow for similar dependencies with
'headers_check', once we properly create the dependencies for those.

We generate an <asm/foo.h> which includes either <asm-$ARCH/foo.h> or
<asm-$ALTARCH/foo.h> as appropriate. But we were doing this dependent on
whether the file in question existed in the _unexported_ tree, not the
exported tree. So if a file was exported to userspace in one asm- directory
but not the other, the generated file in asm/ was incorrect.
This only changed the failure mode if it _was_ included from a nice #error to
a less explicable #include failure -- but it also gave false errors in 'make
headers_check' output. Fix it by looking in the right place instead.

Based on the 'headers_install' target, this performs a basic sanity check
on the exported headers -- so far only checking that they do not include
any other headers which aren't selected for import, but easily extendable.

This adds a make target which exports a subset of headers which contain
definitions which are useful for system libraries and tools. It uses the
BSD 'unifdef' tool to remove instances of #ifdef __KERNEL__, and uses
sed to remove markers like __user.
