65  * There are as many error detector "banks" as indicated by
66  * IA32_MSR_MCG_CAP.COUNT.  Each bank has a minimum of 3 associated
67  * registers (MCi_CTL, MCi_STATUS, and MCi_ADDR) and some banks
68  * may implement a fourth (MCi_MISC) which should only be read
69  * when MCi_STATUS.MISCV indicates that it exists and has valid data.
70  *
71  * The first bank features at MSR offsets 0x400 to 0x403, the next at
72  * 0x404 to 0x407, and so on.  Current processors implement up to 6
73  * banks (sixth one at 0x414 to 0x417).
74  *
75  * It is, sadly, not the case that the i'th set of 4 registers starting
76  * at 0x400 corresponds to MCi_{CTL,STATUS,ADDR,MISC} - for some Intel
77  * processors, for example, the order is 0/1/2/4/3.  Nonetheless, we can
78  * still iterate through the banks and read all telemetry - there'll just
79  * be some potential confusion as to which processor unit a bank is
80  * associated with.  Error reports should seek to disambiguate.
81  *
82  * IA32_MSR_MC(i, which) calculates the MSR address for th i'th bank
83  * of registers (not for MCi_*, as above) and one of CTL, STATUS, ADDR, MISC
