Subject[GIT PULL] x86 NMI diagnostics for v6.3
Hello, Linus,

Please pull the x86 NMI diagnostics series from:

git:// tags/nmi.2023.02.14a
# HEAD: x86/nmi: Print reasons why backtrace NMIs are ignored (2023-01-19 15:55:12 -0800)

This is of course not normally something that would come up through the
-rcu tree, but these have Ingo Molnar's Reviewed-by tag.

NMI diagnostics for v6.3

Add diagnostics to the x86 NMI handler to help detect NMI-handler bugs
on the one hand and failing hardware on the other.

x86/nmi: Accumulate NMI-progress evidence in exc_nmi()
