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.

When a group has multiple events and the leader fails it can yield
errors like:
$ perf stat -e '{uncore_imc/cas_count_read/},instructions' /bin/true
Error:
The sys_perf_event_open() syscall returned with 22 (Invalid argument) for event (uncore_imc/cas_count_read/).
/bin/dmesg | grep -i perf may provide additional information.
However, when not the group leader <not supported> is given:
$ perf stat -e '{instructions,uncore_imc/cas_count_read/}' /bin/true
...
1,619,057 instructions
<not supported> MiB uncore_imc/cas_count_read/
This is necessary because get_group_fd will fail if the leader fails and
is the direct result of the check on line 750 of builtin-stat.c in
stat_handle_error that returns COUNTER_SKIP for the latter case.
This patch improves the error message to:
$ perf stat -e '{uncore_imc/cas_count_read/},instructions' /bin/true
Error:
Invalid event (uncore_imc/cas_count_read/) in per-thread mode, enable system wide with '-a'.
v2. Changed the test to use !target__has_cpu as suggested by Namhyung Kim.

mistakenly got it merged in the perf tools tree, revert it, it'll go via

In 'perf report', entering a recursive function from inside of itself
(either directly of indirectly through some other function) results in
calling symbol__annotate2 multiple() times, and freeing the whole
disassembly when exiting from the innermost instance.
The first issue causes the function's disassembly to be duplicated, and
the latter a heap use-after-free (and crash) when trying to access the
disassembly again.
I reproduced the bug on perf 5.11.22 (Ubuntu 20.04.3 LTS) and 5.16.rc8
with the following testcase (compile with gcc recursive.c -o recursive).
To reproduce:
- perf record ./recursive
- perf report
- enter fibonacci and annotate it
- move the cursor on one of the "callq fibonacci" instructions and press enter
- at this point there will be two copies of the function in the disassembly
- go back by pressing q, and perf will crash
#include <stdio.h>
int fibonacci(int n)
{
if(n <= 2) return 1;
return fibonacci(n-1) + fibonacci(n-2);
}
int main()
{
printf("%d\n", fibonacci(40));
}
This patch addresses the issue by annotating a function and freeing the
associated memory on exit only if no annotation is already present, so
that a recursive function is only annotated on entry.

Sort key 'p_stage_cyc' is used to present the latency cycles spent in
pipeline stages.
perf has local 'p_stage_cyc' sort key to display this info. There is no
global variant available for this sort key. The local variant shows
latency in a single sample, whereas the global value will be useful to
present the total latency (sum of latencies) in the hist entry. It
represents the latency number multiplied by the number of samples.
Add global ('p_stage_cyc') and local variant ('local_p_stage_cyc') for
this sort key. Use 'local_p_stage_cyc' as default option for "mem" sort
mode.
Also add this to the list of dynamic sort keys and made the
"dynamic_headers" and "arch_specific_sort_keys" as static.

- Add support for handling hw errors in SGX pages: poisoning,
recovering from poison memory and error injection into SGX pages
- A bunch of changes to the SGX selftests to simplify and allow of SGX
features testing without the need of a whole SGX software stack
- Add a sysfs attribute which is supposed to show the amount of SGX
memory in a NUMA node, similar to what /proc/meminfo is to normal
memory
- The usual bunch of fixes and cleanups too
