Merge tag 'x86-urgent-2022-08-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull misc x86 fixes from Ingo Molnar: - Fix PAT on Xen, which caused i915 driver failures - Fix compat INT 80 entry crash on Xen PV guests - Fix 'MMIO Stale Data' mitigation status reporting on older Intel CPUs - Fix RSB stuffing regressions - Fix ORC unwinding on ftrace trampolines - Add Intel Raptor Lake CPU model number - Fix (work around) a SEV-SNP bootloader bug providing bogus values in boot_params->cc_blob_address, by ignoring the value on !SEV-SNP bootups. - Fix SEV-SNP early boot failure - Fix the objtool list of noreturn functions and annotate snp_abort(), which bug confused objtool on gcc-12. - Fix the documentation for retbleed * tag 'x86-urgent-2022-08-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: Documentation/ABI: Mention retbleed vulnerability info file for sysfs x86/sev: Mark snp_abort() noreturn x86/sev: Don't use cc_platform_has() for early SEV-SNP calls x86/boot: Don't propagate uninitialized boot_params->cc_blob_address x86/cpu: Add new Raptor Lake CPU model number x86/unwind/orc: Unwind ftrace trampolines with correct ORC entry x86/nospec: Fix i386 RSB stuffing x86/nospec: Unwreck the RSB stuffing x86/bugs: Add "unknown" reporting for MMIO Stale Data x86/entry: Fix entry_INT80_compat for Xen PV guests x86/PAT: Have pat_enabled() properly reflect state when running on Xen
