This reverts commit Fixes: ac2dc29edd ("perf stat: Add default
hybrid events")
Between this patch and the reverted patch, the commit 6c1912898e
("perf parse-events: Rename parse_events_error functions") and the
commit 07eafd4e05 ("perf parse-event: Add init and exit to
parse_event_error") clean up the parse_events_error_*() codes. The
related change is also reverted.
The reverted patch is hard to be extended to support new default events,
e.g., Topdown events, and the existing "--detailed" option on a hybrid
platform.
A new solution will be proposed in the following patch to enable the
perf stat default on a hybrid platform.

On linux-next tree 'perf test 95' ("Check branch stack sampling") was
added recently.
s390 does not support branch sampling at all and the test case fails
despite for checking branch support before hand.
The check for support of branching uses the software event named "dummy",
as seen in the line:
perf record -b -o- -e dummy -B true > /dev/null 2>&1 || exit 2
However when the branch recording is actually done, a different event is
used, as seen in the line:
perf record -o $TMPDIR/... --branch-filter any,save_type,u -- ...
The event is omitted and for "perf record" the default event is cycles,
which is not supported by s390 and this fails when executed on s390:
# perf record --branch-filter any,save_type,u -- /tmp/__perf_test.program.iDSmQ/a.out
Error:
cycles: PMU Hardware or event type doesn't support branch stack sampling.
#
Therefore fix this and use the same event cycles for testing support
and actually running the test.
Output before:
# ./perf test -Fv 95
95: Check branch stack sampling :
--- start ---
Testing user branch stack sampling
---- end ----
Check branch stack sampling: FAILED!
#
Output after:
# ./perf test -Fv 95
95: Check branch stack sampling :
--- start ---
---- end ----
Check branch stack sampling: Skip
#

Add PMU events for the Arm Cortex-A78C and Arm Cortex-X1C CPUs.
Events for Arm Cortex-A78C match those for Arm Cortex-A78.
Events for Arm Cortex-X1C match those for Arm Cortex- X1.
As such, this is just a mapfile change.
Main ID Register (MIDR) and event data is sourced from the corresponding
Arm Technical Reference Manuals:

Update to v9, the metrics are based on TMA 4.4 full.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
to download and generate the latest events and metrics. Manually copy
the knightslanding files into perf and update mapfile.csv.
Tested on a non-knightslanding with 'perf test':

10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok
Note: uncore-memory has become uncore-other as the topic was
determined this way in the conversion scripts. For simplicity the
scripts naming is maintained.

Commit 824ddc601a ("userfaultfd: provide unmasked address on
page-fault") was introduced to fix an old bug, in which the offset in the
address of a page-fault was masked. Concerns were raised - although were
never backed by actual code - that some userspace code might break because
the bug has been around for quite a while. To address these concerns a
new flag was introduced, and only when this flag is set by the user,
userfaultfd provides the exact address of the page-fault.
The commit however had a bug, and if the flag is unset, the offset was
always masked based on a base-page granularity. Yet, for huge-pages, the
behavior prior to the commit was that the address is masked to the
huge-page granulrity.
While there are no reports on real breakage, fix this issue. If the flag
is unset, use the address with the masking that was done before.

Icelake has a slots event, on my Skylakex I have CPU events in sysfs of
topdown-slots-issued and topdown-total-slots.
Legacy event parsing would try to use '-' to separate parts of an event
and so perf_pmu__parse_init sets 'slots' to be a
PMU_EVENT_SYMBOL_SUFFIX2.
As such parsing the slots event for a fake PMU fails as a
PMU_EVENT_SYMBOL_SUFFIX2 isn't made into the PE_PMU_EVENT_FAKE token.
Resolve this issue by test initializing the PMU parsing state before
every parse. This must be done every parse as the state is removes after
each parse_events.

'perf record' generates perf.data, which generates extra interrupts
for hard disk, amount of data to be collected increases with time.
Using eBPF trace can process the data in kernel, which solves the
preceding two problems.
Add -b/--use-bpf option for latency and report to support
tracing kwork events using eBPF:
1. Create bpf prog and attach to tracepoints,
2. Start tracing after command is entered,
3. After user hit "ctrl+c", stop tracing and report,
4. Support CPU and name filtering.
This commit implements the framework code and
does not add specific event support.
Test cases:
# perf kwork rep -h
Usage: perf kwork report [<options>]
-b, --use-bpf Use BPF to measure kwork runtime
-C, --cpu <cpu> list of cpus to profile
-i, --input <file> input file name
-n, --name <name> event name to profile
-s, --sort <key[,key2...]>
sort by key(s): runtime, max, count
-S, --with-summary Show summary with statistics
--time <str> Time span for analysis (start,stop)
# perf kwork lat -h
Usage: perf kwork latency [<options>]
-b, --use-bpf Use BPF to measure kwork latency
-C, --cpu <cpu> list of cpus to profile
-i, --input <file> input file name
-n, --name <name> event name to profile
-s, --sort <key[,key2...]>
sort by key(s): avg, max, count
--time <str> Time span for analysis (start,stop)
# perf kwork lat -b
Unsupported bpf trace class irq
# perf kwork rep -b
