[PATCH] x86_64/i386: Compute correct MTRR mask on early Noconas
Force correct address space size for MTRR on some 64bit Intel Xeons
They report 40bit, but only have 36bits of physical address space.
This caused problems with setting up the correct masks for MTRR,
resulting in incorrect MTRRs.
CPUID workaround for steppings 0F33h(supporting x86) and 0F34h(supporting x86
and EM64T). Detail info can be found at:
