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.
