Subject: [git pull] x86 changes for v2.6.26, part two
Linus, please pull the latest x86 git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86.git for-linus
the tree touches the following generic files:
include/linux/efi.h | 7 +
include/linux/irqflags.h | 6 +-
include/linux/prctl.h | 6 +
kernel/fork.c | 35 ++-
kernel/sys.c | 13 +-
kernel/time/timekeeping.c | 2 +
these are for changes that have their main (only) use in arch/x86 - the
fork.c impact is for lazy FPU state allocation. Cross-build test results
are at:
http://www.tglx.de/autoqa-cgi/index?run=88&tree=1
Thanks,
Ingo
