On AML SOCs (for Nocturne), we have seen MCEs being dumped after booting to kernel. After debugging i found MCAs were not cleared before booting the kernel so i pushed those 2 patches and with that kernel was not reporting MCEs.

(I am trying to find the crosbug but i am not able to access them, seems like i have some access issues)

@Subrata, Have you checked on SKL/KBL/AML platforms that MCEs are not dumped if you dont clear them before booting?

Clearing from cpu.c might be too early, i think. in my understanding, Clearing MCEs at that point is needed only if we need to enable SGX, as when we reload microcode for SGX we need have MCA clean.
