Merge tag 'x86-urgent-2025-07-20' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 bug fix from Thomas Gleixner:
 "A single fix for a GCC wreckage, which emits a KCSAN instrumentation
  call in __sev_es_nmi_complete() despite the function being annotated
  with 'noinstr'.

  As all functions in that source file are noinstr, exclude the whole
  file from KCSAN in the Makefile to cure it"
