[PATCH 0/2] Fixes for recent x86/boot rip-relative addressing changes

[Tom Lendacky]

This patch series provides fixes for the recent x86/boot rip-relative
addressing changes that causes system crashes when booting with 5-level
pagetables and SME active.

I thought I had tested 5-level paging with SME, but must have missed
it. There are two patches to fix the issues that can be squashed into
a single patch with multiple Fixes: tags if desired.

The second patch is sort of a revert, but instead uses the newer
RIP_REL_REF() macro instead of reverting the fix and continuing to use
the fixup_pointer() support.
