Pull GHES changes for 4.2 from Borislav Petkov:
"GHES: Seriously speedup and cleanup NMI handler (Jiri Kosina and Borislav Petkov)
This is the result of us seeing this during boot
[ 24.332560] INFO: NMI handler (ghes_notify_nmi) took too long to run: 3.265 msecs
[ 24.332567] INFO: NMI handler (ghes_notify_nmi) took too long to run: 5.946 msecs
[ 24.332568] INFO: NMI handler (ghes_notify_nmi) took too long to run: 5.948 msecs
and a report of people running perf stat and the machine softlocking.
"hest_disable" was helping in this case, which made us look at that
particular NMI handler. It was grabbing a lock each time it is run and
on each CPU. But this is not needed as the GHES sources are global and
they need only a single reader.
This patchset does that and cleans up the handler in the process."
