- Fix some aspects of building with an older (than the one in the
kernel sources) libbpf present in a distro, when building with
LIBBPF_DYNAMIC=1.
- Fix errno setting races with event_fd and the signal handler in 'perf
record'.
- Fix Power10 hv-24x7 metric events when some events may have a zero
count based on system configuration.
- Do not fail Intel-PT misc test w/o libpython, just skip it.
- Fix incorrect arm64 Hisi hip08 L3 metrics (IF_BP_MISP_BR_RET,
IF_BP_MISP_BR_RET, IF_BP_MISP_BR_BL) due to mistakes in the
documentation used to generate the JSON files for these metrics.
- Fix auxtrace (Intel PT, ARM Coresight) address filter symbol name
match for modules, we need to skip the module name.
- Sync copies of files with the kernel sources, including ppc syscall
tables and assorted headers, some resulting in tools being able to
decode new network protocols (IPPROTO_L2TP) and statx masks
(STATX_DIOALIGN).
- Fix PMU name pai_crypto in the vendor events file (JSON) for s390.
- Fix man page build wrt perf-arm-coresight.txt as the build process
assumes files starting with 'perf-' are man pages, and this file
isn't one.

"A collection of mostly unremarkable fixes for SPI that have built up

The change to the qup adding support for GPIO chip selects is fixing a
regression due to the removal of legacy GPIO handling, the driver had
previously been silently relying on the legacy GPIO support in a
slightly broken way which worked well enough on some systems. Fixing
it is simply a case of setting a couple of bits of information in the

Commit e0b23af82d ("perf list: Add PMU pai_crypto event
description for IBM z16") introduced the "Processor Activity
Instrumentation" for cryptographic counters for z16. The PMU device
driver exports the counters via sysfs files listed in directory
/sys/devices/pai_crypto.
To specify an event from that PMU, use 'perf stat -e pai_crypto/XXX/'.
However the JSON file mentioned in above commit exports the counter
decriptions in file pmu-events/arch/s390/cf_z16/pai.json. Rename this
file to pmu-events/arch/s390/cf_z16/pai_crypto.json to make the naming
consistent.
Now 'perf list' shows the counter names under pai_crypto section:
pai_crypto:
CRYPTO_ALL
[CRYPTO ALL. Unit: pai_crypto]
...
Output before was
pai:
CRYPTO_ALL
[CRYPTO ALL. Unit: pai_crypto]
...

During the transition to libbpf 1.0 some functions that perf used were
deprecated and finally removed from libbpf, so bpf_program__set_insns()
was introduced for perf to continue to use its bpf loader.
But when build with LIBBPF_DYNAMIC=1 we now need to check if that
function is available so that perf can build with older libbpf versions,
even if the end result is emitting a warning to the user that the use
of the perf BPF loader requires a newer libbpf, since bpf_program__set_insns()
touches libbpf objects internal state.
This affects only 'perf trace' when using bpf C code or pre-compiled
bytecode as an event.
Noticed on RHEL9, that has libbpf 0.7.0, where bpf_program__set_insns()
isn't available.

The bpf_load_program() prototype appeared in tools/lib/bpf/bpf.h as
deprecated, but nowadays its completely removed, so add it back for
building with the system libbpf when using 'make LIBBPF_DYNAMIC=1'.
This is a stop gap hack till we do like tools/bpf does with bpftool,
i.e. bootstrap the libbpf build and install it in the perf build
directory when not using 'make LIBBPF_DYNAMIC=1'.
That has to be done to all libraries in tools/lib/, so tha we can
remove -Itools/lib/ from the tools/perf CFLAGS.
Noticed when building with LIBBPF_DYNAMIC=1 and libbpf 0.7.0 on RHEL9.

Testcase stat_all_metrics.sh fails in powerpc:
90: perf all metrics test : FAILED!
The testcase "stat_all_metrics.sh" verifies perf stat result for all the
metric events present in perf list. It runs perf metric events with
various commands and expects non-empty metric result.
Incase of powerpc:hv-24x7 events, some of the event count can be 0 based
on system configuration. And if that event used as denominator in divide
equation, it can cause divide by 0 error. The current nest_metric.json
file creating divide by 0 issue for some of the metric events, which
results in failure of the "stat_all_metrics.sh" test case.
Most of the metrics events have cycles or an event which expect to have
a larger value as denominator, so adding 1 to the denominator of the
metric expression as a fix.
Result in powerpc box after this patch changes:
90: perf all metrics test : Ok
Fixes: a3cbcadfdf ("perf vendor events power10: Adds 24x7 nest metric events for power10 platform")
