The variable CFLAGS is a wellknown variable and the usage by
kbuild may result in unexpected behaviour.
On top of that several people over time has asked for a way to
pass in additional flags to gcc.
This patch replace use of CFLAGS with KBUILD_CFLAGS all over the
tree and enabling one to use:
make CFLAGS=...
to specify additional gcc commandline options.
One usecase is when trying to find gcc bugs but other
use cases has been requested too.
Patch was tested on following architectures:
alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k
Test was simple to do a defconfig build, apply the patch and check
that nothing got rebuild.

The generic board stubs were never added, and the ROM-RAM boards
never made it in to the wild. Neither one has any users, and both
are utterly broken in-tree (likely since 2.4). Kill them both off.

The original sh64 toolchains required that we tune the ISA
level accordingly to not have head.S/entry.S blow up. With
current toolchains, this is no longer the case, and the
syntax magically changed as well, causing all current
toolchains to die a horrible death.
Incidentally, code generation in other parts of the kernel
is now significantly complex enough that none of the older
toolchains make it very far these days, so there's not
even any point in preserving legacy compatability via
as-option.
This fixes a long-standing issue, as noted here:
http://lkml.org/lkml/2005/1/5/223
Though at the time the current toolchains were too broken
to make adjusting the tuning worthwhile.

When introducing the generic asm-offsets.h support the dependency
chain for the prepare targets was changed. All build scripts expecting
include/asm/asm-offsets.h to be made when using the prepare target would broke.
With the limited number of prepare targets left in arch Makefiles
the trivial solution was to introduce a new arch specific target: archprepare
The dependency chain looks like this now:
prepare
|
+--> prepare0
|
+--> archprepare
|
+--> scripts_basic
+--> prepare1
|
+---> prepare2
|
+--> prepare3
So prepare 3 is processed before prepare2 etc.
This guaantees that the asm symlink, version.h, scripts_basic
are all updated before archprepare is processed.
prepare0 which build the asm-offsets.h file will need the
actions performed by archprepare.
The head target is now named prepare, because users scripts will most
likely use that target, but prepare-all has been kept for compatibility.
Updated Documentation/kbuild/makefiles.txt.

h8300, m68knommu, sh and sh64 all used the name asm-offsets.h so minimal
changes required.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
