Subject: [GIT PULL] Performance events updates for v2.6.36
Linus,
Please pull the latest perf-core-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git perf-core-for-linus
Lots of updates. Note that it also includes the new generic soft/hard watchdog
code and adds it for x86.
Thanks,
Ingo
