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.
