The board file using this driver has been deleted and the
FSG3 LEDs can be modeled using a system controller and some
register bit LEDs in the device tree so this driver is no
longer needed.

This patch changes MetricExpr to be written out in the same case. This
enables events in metrics to use modifiers like 'G' which currently
yield parse errors when made lower case. To keep tests passing the
literal #smt_on is compared in a non-case sensitive way - #SMT_on is
present in at least SkylakeX metrics.

[ Fixed up perf_cpu conflict, i.e. we need to append ".cpu" to cpu__max_present_cpu() result ]
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
While I was auditing the code in xfs_repair that adds feature bits to
existing V5 filesystems, I decided to have a look at how online fsck
handles feature bits, and I found a few problems:
1) ATTR2 is added to the primary super when an xattr is set to a file,
but that isn't consistently propagated to secondary supers. This isn't
a corruption, merely a discrepancy that repair will fix if it ever has
to restore the primary from a secondary. Hence, if we find a mismatch
on a secondary, this is a preen condition, not a corruption.
2) There are more compat and ro_compat features now than there used to
be, but we mask off the newer features from testing. This means we
ignore inconsistencies in the INOBTCOUNT and BIGTIME features, which is
wrong. Get rid of the masking and compare directly.
3) NEEDSREPAIR, when set on a secondary, is ignored by everyone. Hence
a mismatch here should also be flagged for preening, and online repair
should clear the flag. Right now we ignore it due to (2).
4) log_incompat features are ephemeral, since we can clear the feature
bit as soon as the log no longer contains live records for a particular
log feature. As such, the only copy we care about is the one in the
primary super. If we find any bits set in the secondary super, we
should flag that for preening, and clear the bits if the user elects to
repair it.

A common problem is confusing CPU map indices with the CPU, by wrapping
the CPU with a struct then this is avoided. This approach is similar to
atomic_t.
Committer notes:
To make it build with BUILD_BPF_SKEL=1 these files needed the
conversions to 'struct perf_cpu' usage:
tools/perf/util/bpf_counter.c
tools/perf/util/bpf_counter_cgroup.c
tools/perf/util/bpf_ftrace.c
Also perf_env__get_cpu() was removed back in "perf cpumap: Switch
cpu_map__build_map to cpu function".
Additionally these needed to be fixed for the ARM builds to complete:
tools/perf/arch/arm/util/cs-etm.c
tools/perf/arch/arm64/util/pmu.c

Synchronize the caller in evsel with the called function.
Shorten 3 lines of code in bperf_read by using
perf_cpu_map__for_each_cpu().
This code is frequently using variables named cpu as cpu map indices,
which doesn't matter as all CPUs are in the CPU map. It is strange in
some cases the cpumap is used at all.
Committer notes:
Found when building with BUILD_BPF_SKEL=1:
Remove unused 'num_cpu' variable in bperf__read().
Make 'j' an 'int' as it is used in perf_cpu_map__for_each_cpu() to compare against an 'int'

Previously evlist__for_each_cpu() needed to iterate over the evlist in
an inner loop and call "skip" routines. Refactor this so that the
iteratr is smarter and the next function can update both the current CPU
and evsel.
By using a cpu map index, fix apparent off-by-1 in __run_perf_stat's
call to perf_evsel__close_cpu().

Passing the number of CPUs and threads allows for an evsel's counts to
be mismatched to its cpu map. To avoid this always derive the counts
size from the cpu map. Change openat-syscall-all-cpus to set the cpus
to allow for this to work.

With no aggregration, such as 'perf stat -A', the aggr_cpu_id lacks a
way to describe per CPU aggregation and the core is set to the CPU in
places like print_counter_aggrdata in stat-display.c.
Setting the core to the CPU is undesirable as the CPU will exceed valid
core values and lead to confusion. Add a CPU variable to address this.
