of: unittest: add program to process EXPECT messages
If unittest detects a problem it will print a warning or error message
to the console. Unittest also triggers warning and error messages from
other kernel code as a result of intentionally bad unittest data. This
has led to confusion as to whether the triggered messages are an
expected result of a test or whether there is a real problem that is
independent of unittest.
EXPECT messages were added to unittest to report each triggered message
that is expected, resulting in verbose console output.
scripts/dtc/of_unittest is a new program that processes the EXPECT

Pull ftrace fix from Steven Rostedt:
"Fix s390 breakage from sorting mcount tables.
The latest merge of the tracing tree sorts the mcount table at build
time. But s390 appears to do things differently (like always) and
replaces the sorted table back to the original unsorted one. As the
ftrace algorithm depends on it being sorted, bad things happen when it
is not, and s390 experienced those bad things.
Add a new config to tell the boot if the mcount table is sorted or
not, and allow s390 to opt out of it"

ftrace: Fix assuming build time sort works for s390
ftrace: Fix assuming build time sort works for s390
To speed up the boot process, as mcount_loc needs to be sorted for ftrace
to work properly, sorting it at build time is more efficient than boot up
and can save milliseconds of time. Unfortunately, this change broke s390
as it will modify the mcount_loc location after the sorting takes place
and will put back the unsorted locations. Since the sorting is skipped at
boot up if it is believed that it was sorted at run time, ftrace can crash
as its algorithms are dependent on the list being sorted.
Add a new config BUILDTIME_MCOUNT_SORT that is set when
BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine
if sorting should take place at boot up.

perf test: Add pmu-events test for aliases with hyphens
Add a test for aliases with hyphens in the name to ensure that the
pmu-events tables are as expects. There should be no reason why these sort
of aliases would be treated differently, but no harm in checking.

perf evsel: Override attr->sample_period for non-libpfm4 events
A previous patch preventing "attr->sample_period" values from being
overridden in pfm events changed a related behaviour in arm-spe.
Before said patch:
perf record -c 10000 -e arm_spe_0// -- sleep 1
Would yield an SPE event with period=10000. After the patch, the period
in "-c 10000" was being ignored because the arm-spe code initializes
sample_period to a non-zero value.
This patch restores the previous behaviour for non-libpfm4 events.
