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
---------------------------------------------------------------- Michael Kelley (1): x86/ioremap: Fix page aligned size calculation in __ioremap_caller()
Pawan Gupta (2): x86/tsx: Add a feature bit for TSX control MSR support x86/pm: Add enumeration check before spec MSRs save/restore setup
Peter Gonda (1): virt/sev-guest: Prevent IV reuse in the SNP guest driver
