Subject: [git pull] x86 fixes


Linus, please pull the latest x86 git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86.git

4 commits: a Kconfig fix for CONFIG_M8K, a warning-message printout 
tweak/fix, and two section fixes. This empties the x86 queue of pending 
2.6.24 fixes for now. Thanks,

	Ingo
