Recoverable Address LSB (bits 5:0): The lowest valid recoverable address bit.
Indicates the position of the least significant bit (LSB) of the recoverable error
address. For example, if the processor logs bits [43:9] of the address, the LSB
sub-field in IA32_MCi_MISC is 01001b (9 decimal). For this example, bits [8:0]
of the recoverable error address in IA32_MCi_ADDR should be ignored.

Address Mode (bits 8:6): Address mode for the address logged in
IA32_MCi_ADDR. The supported address modes are given in Table 15-3.

_CTL2 MSRs
The IA32_MCi_CTL2 MSR provides the programming interface to use
corrected MC error signaling capability that is indicated by
IA32_MCG_CAP[10] = 1. Software must check for the presence of
IA32_MCi_CTL2 on a per-bank basis.
