Comparing with 2.6.27, cpu2000 (both float and int) has about 13% regression
with 2.6.28-rc1 on my new-model x86-64 machine.

I bisected down to below patch.

commit 0afe2db21394820d32646a695eccf3fbfe6ab5c7
Merge: d847059... 43603c8...

    Merge branch 'x86/unify-cpu-detect' into x86-v28-for-linus-phase4-D
    
    Conflicts:
        arch/x86/kernel/cpu/common.c
        arch/x86/kernel/signal_64.c
        include/asm-x86/cpufeature.h


When I tried to revert it against 2.6.28-rc2, there are many conflictions.

Ingo,
Is it possible to break it to small patches, so we can locate the bad source lines?
