Merge tag 'x86_urgent_for_v6.2_rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Borislav Petkov:
- Start checking for -mindirect-branch-cs-prefix clang support too now
that LLVM 16 will support it
- Fix a NULL ptr deref when suspending with Xen PV
- Have a SEV-SNP guest check explicitly for features enabled by the
hypervisor and fail gracefully if some are unsupported by the guest
instead of failing in a non-obvious and hard-to-debug way
- Fix a MSI descriptor leakage under Xen
- Mark Xen's MSI domain as supporting MSI-X
- Prevent legacy PIC interrupts from being resent in software by
marking them level triggered, as they should be, which lead to a NULL
ptr deref
