[git pull] scheduler changes for v2.6.26
From: Ingo Molnar
Date: Sat Apr 19 2008 - 14:13:23 EST
Linus, please pull the latest scheduler git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/mingo/linux-2.6-sched-devel.git for-linus
The cpumask changes (needed for 4096 CPU support) also touch the x86
tree - the recent x86.git pull i sent will cleanly merge with this tree,
in either order. The only real complication the 4K CPU related changes
have are in the scheduler code - that's why they were merged and tested
in this tree. They have wider API impact than the scheduler but those
are straightforward/trivial. It was all tested in linux-next as well.
Thanks!
Ingo
