Subject: x86/mce: Remove check for CONFIG_X86_MCE_P4THERMAL

The Kconfig symbol X86_MCE_P4THERMAL was removed in v2.6.32.
Remove a useless check for its macro, as it will now always
evaluate to false.

Subject: x86, reloc: Use xorl instead of xorq in relocate_kernel_64.S

There is no point in using "xorq" to clear a register... use "xorl" to
clear the bottom 32 bits, and the upper 32 bits get cleared by virtue
of zero extension.
