Linus Torvalds c23719abc3 Miscellaneous x86 fixes: 
- Fix SEV guest boot failures in certain circumstances, due
    to very early code relying on a BSS-zeroed variable that
    isn't actually zeroed yet an may contain non-zero bootup
    values. Move the variable into the .data section go gain
    even earlier zeroing.
 
  - Expose & allow the IBPB-on-Entry feature on SNP guests,
    which was not properly exposed to guests due to initial
    implementational caution.
 
  - Fix O= build failure when CONFIG_EFI_SBAT_FILE is using
    relative file paths.
 
  - 4 commits to fix the various SNC (Sub-NUMA Clustering)
    topology enumeration bugs/artifacts (sched-domain build
    errors mostly). SNC enumeration data got more complicated
    with Granite Rapids X (GNR) and Clearwater Forest X (CWF),
    which exposed these bugs and made their effects more
    serious.
 
  - Also use the now sane(r) SNC code to fix resctrl SNC
    detection bugs.
 
  - Work around a historic libgcc unwinder bug in the vdso32
    sigreturn code (again), which regressed during an overly
    aggressive recent cleanup of DWARF annotations.
