Subject: [regression][bisected] ~90,000 wakeups as of 2.6.26-rc3

Hi,

there is a problem in 2.6.26-rc3 which was not there in case of
2.6.25: the CPU wakes up ~90,000 times per sec instead of ~60 per sec.

I also "git bisected" the problem, the result is:

6e908947b4995bc0e551a8257c586d5c3e428201 is first bad commit
commit 6e908947b4995bc0e551a8257c586d5c3e428201

    x86: fix ioapic bug again

    un-revert:

     commit 4960c9df1407c2723459c60ff13e6efe0c209c62
     Author: Thomas Gleixner <tglx@...utronix.de>
     Date:   Tue Jan 22 10:23:01 2008 +0100

         Revert "x86: fix NMI watchdog & 'stopped time' problem"

             This reverts commit d4d25deca49ec2527a634557bf5a6cf449f85deb.

    needs a proper fix though ...
