AMD systems currently lay out MCA bank types such that the type of bank
number "i" is either the same across all CPUs or is Reserved/Read-as-Zero.
For example:
Bank # | CPUx | CPUy
0 LS LS
1 RAZ UMC
2 CS CS
3 SMU RAZ
Future AMD systems will lay out MCA bank types such that the type of
bank number "i" may be different across CPUs.
For example:
Bank # | CPUx | CPUy
0 LS LS
1 RAZ UMC
2 CS NBIO
3 SMU RAZ
Change the structures that cache MCA bank types to be per-CPU and update
smca_get_bank_type() to handle this change.
Move some SMCA-specific structures to amd.c from mce.h, since they no
longer need to be global.
Break out the "count" for bank types from struct smca_hwid, since this
should provide a per-CPU count rather than a system-wide count.
Apply the "const" qualifier to the struct smca_hwid_mcatypes array. The
values in this array should not change at runtime.
