- 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.
