Subject: microblaze: commit 95521585 breakage

Hi Sam, Michal,

Your MicroBlaze arch makefile cleanup commit
9552158573f847aa429334bb97995bb290bb4b0d had a rather unfortunate
error in it:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=950b260ed21fdb6fa5f18485dabb0b03488431fa

You intended to change CFLAGS_KERNEL to KBUILD_CFLAGS, but instead
changed CFLAGS_KERNEL to KBUILD_KERNEL.

The result?  No CPU feature optimisations across the entire MicroBlaze
kernel build :(

The fix is trivial - may I leave it to you to resolve and merge as
soon as possible?  This is a pretty serious performance regression.

Thanks,

John
