Merge tag 'x86-urgent-2026-03-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 fixes from Ingo Molnar:

 - Fix an early boot crash in AMD SEV-SNP guests, caused by incorrect
   FSGSBASE init ordering (Nikunj A Dadhania)

 - Remove X86_CR4_FRED from the CR4 pinned bits mask, to fix a race
   window during the bootup of SEV-{ES,SNP} or TDX guests, which can
   crash them if they trigger exceptions in that window (Borislav
   Petkov)

 - Fix early boot failures on SEV-ES/SNP guests, due to incorrect early
   GHCB access (Nikunj A Dadhania)

 - Add clarifying comment to the CRn pinning logic, to avoid future
   confusion & bugs (Peter Zijlstra)
