[PATCH] x86_64: 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. CPUID workaround for steppings 0F33h(supporting x86) and 0F34h(supporting x86 and EM64T).
