Merge tag 'x86_urgent_for_v5.18_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Borislav Petkov:
- Fix the MSI message data struct definition
- Use local labels in the exception table macros to avoid symbol
conflicts with clang LTO builds
- A couple of fixes to objtool checking of the relatively newly added
SLS and IBT code
- Rename a local var in the WARN* macro machinery to prevent shadowing
