Joerg Roedel 62b97630d4 UPSTREAM: x86/sev: Check IOBM for IOIO exceptions from user-space 
Upstream commit: b9cb9c45583b911e0db71d09caa6b56469eb2bdf

Check the IO permission bitmap (if present) before emulating IOIO #VC
exceptions for user-space. These permissions are checked by hardware
already before the #VC is raised, but due to the VC-handler decoding
race it needs to be checked again in software.

Bug: 309733863
Fixes: 25189d08e5 ("x86/sev-es: Add support for handling IOIO exceptions")
