Modified Files:
        src/sys/arch/x86/x86: identcpu.c

Log Message:
On certain AMD f10h CPUs (like mine), the BIOS does not enable WC+. It
means that the guest pages that are WC+ become CD, and this degrades
performance of the guests.

Explicitly enable WC+.

While here clarify the AMD identification code.
