Convert test exclusion into test skipping. This brings the logic for why a test is being skipped into the test itself, instead of having to spread ifdefs around the code. This will make cleanup easier as minimum tests get raised. Drop __maybe_unused so missed tests will be noticed again and clean up whitespace.

Commit e0b23af8 ("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.

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.

This is a re-do of commit e0e0747d ("scsi: mpt3sas: Fix return value check of dma_get_required_mask()"), which I ended up undoing in a mis-merge in commit 62e6e594 ("Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi"). The original commit message was scsi: mpt3sas: Fix return value check of dma_get_required_mask() Fix the incorrect return value check of dma_get_required_mask(). Due to this incorrect check, the driver was always setting the DMA mask to 63 bit.
