Pull x86 fixes from Ingo Molnar: - 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 - 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 * tag 'x86-urgent-2026-03-08' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/entry/vdso32: Work around libgcc unwinder bug x86/resctrl: Fix SNC detection x86/topo: Fix SNC topology mess x86/topo: Replace x86_has_numa_in_package x86/topo: Add topology_num_nodes_per_package() x86/numa: Store extra copy of numa_nodes_parsed x86/boot: Handle relative CONFIG_EFI_SBAT_FILE file paths x86/sev: Allow IBPB-on-Entry feature for SNP guests x86/boot/sev: Move SEV decompressor variables into the .data section
