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"
