Initial driver for PMU event counting on the Arm CMN-600 interconnect.
CMN sports an obnoxiously complex distributed PMU system as part of
its debug and trace features, which can do all manner of things like
sampling, cross-triggering and generating CoreSight trace. This driver
covers the PMU functionality, plus the relevant aspects of watchpoints
for simply counting matching flits.Tested-by: Tsahi Zidenberg

Pull Documentation updates from Jonathan Corbet:
"Here are the main documentation changes for 5.5:- Various kerneldoc script enhancements.
- More RST conversions; those are slowing down as we run out of
things to convert, but we're a ways from done still.- Dan's "maintainer profile entry" work landed at last. Now we just
need to get maintainers to fill in the profiles...- A reworking of the parallel build setup to work better with a
variety of systems (and to not take over huge systems entirely in
particular).- The MAINTAINERS file is now converted to RST during the build.
Hopefully nobody ever tries to print this thing, or they will need
to load a lot of paper.- A script and documentation making it easy for maintainers to add
Link: tags at commit time.Also included is the removal of a bunch of spurious CR characters"
