Regression in 2.6.36-rc1 bisected to commit 9d8888c

[Larry Finger]

With 2.6.36-rc1 from the mainline git tree, my x86_64 system running on an AMD
Turion 64 x2 TL-60 has required pressing keys to get booting to advance. This
behavior begins as soon as the kernel is loaded. I bisected the problem to:

commit 9d8888c2a214aece2494a49e699a097c2ba9498b

    x86, cpu: Clean up AMD erratum 400 workaround

    Remove check_c1e_idle() and use the new AMD errata checking framework
    instead.

Reverting this patch allows the current 2.6.36-rc1+ to boot normally.

This problem is entered into the Kernel Bugzilla as Bug #16636.
