Two fixes for x86:
- Map EFI runtime service data as encrypted when SEV is enabled otherwise
e.g. SMBIOS data cannot be properly decoded by dmidecode.
- Remove the warning in the vector management code which triggered when a
managed interrupt affinity changed outside of a CPU hotplug
operation. The warning was correct until the recent core code change
that introduced a CPU isolation feature which needs to migrate managed
interrupts away from online CPUs under certain conditions to achieve the
isolation.
