Subject: [PATCH/RFT 0/2] regression fix: "smpboot: do_boot_cpu failed(-1) to wakeup CPU#1"

Shane, Donald,
Please test this pair of patches.

If the default kernel still has a problem booting CPU #1 on yoru Core2 system,
"cpu_init_udelay=10000" should get you back to the legacy delays.

thanks,
Len Brown, Intel Open Source Technology Center
