Subject: [RFC - GIT pull] first step to get rid of x86_64 and i386 dirs
Hi Ingo.
This is first step in getting rid of the two directories.
I had to do some very minor modifications in common files
to let it work out - but nothing really hackish.
If you & Thomas + hpa are OK with the changes they can be
pulled from:
git://git.kernel.org/pub/scm/linux/kernel/git/sam/x86.git
As this is mostly renames I have attached a git -M diff only.
The remaining stuff is Kconfig files.
Before looking into these I am hoping someone could
step in and make the two Kconfig.debug
files 100% equal - because then I can fix the kconfig
stuff and finally kill the two directories.
Sam

x86: move defconfig files for i386 and x86_64 to x86
With some small changes to kconfig makefile we can now
locate the defconfig files for i386 and x86_64 in
the configs/ subdirectory under x86.

x86: move i386 and x86_64 Makefiles to arch/x86
Moving the ARCH specific MAkefiles for i386 and x86_64
required a litle bit tweaking in the top-lvel Makefile.
But this is one of the final steps to get rid of the
x86_64 and i386 directories.
