configurations exposed as CPUID 2 descriptors:

61H Instruction TLB: 4 KByte pages, fully associative, 48 entries
63H Data TLB: 1 GByte pages, 4-way set associative, 4 entries
76H Instruction TLB: 2M/4M pages, fully associative, 8 entries
B5H Instruction TLB: 4KByte pages, 8-way set associative, 64 entries
B6H Instruction TLB: 4KByte pages, 8-way set associative, 128 entries
C1H Shared 2nd-Level TLB: 4 KByte/2MByte pages, 8-way associative, 1024 entries
C2H DTLB DTLB: 2 MByte/$MByte pages, 4-way associative, 16 entries

Let's detect them as well.
