  x86/ioremap: Fix page aligned size calculation in __ioremap_caller() (2022-11-22 12:21:16 +0100)

----------------------------------------------------------------
- ioremap: mask out the bits which are not part of the physical address
*after* the size computation is done to prevent and hypothetical ioremap
failures

- Change the MSR save/restore functionality during suspend to rely on
flags denoting that the related MSRs are actually supported vs reading
them and assuming they are (an Atom one allows reading but not writing,
thus breaking this scheme at resume time.)

- prevent IV reuse in the AES-GCM communication scheme between SNP
guests and the AMD secure processor
