Linus Torvalds b1412bd75a perf tools changes for v5.14: 2nd batch
New features:
 
 - Enable use of BPF counters with 'perf stat --for-each-cgroup', using per-CPU
   'cgroup-switch' events with an attached BPF program that does aggregation
   per-cgroup in the kernel instead of using per-cgroup perf events.
 
 - Add Topdown metrics L2 events as default events in 'perf stat' for systems
   having those events.
 
 Hardware tracing:
 
 - Add a config for max loops without consuming a packet in the Intel PT packet
   decoder, set via 'perf config intel-pt.max-loops=N'
 
 Hardware enablement:
 
 - Disable misleading NMI watchdog message in 'perf stat' on hybrid systems
   such as Intel Alder Lake.
 
 - Add a dummy event on hybrid systems to collect metadata records.
 
 - Add 24x7 nest metric events for the Power10 platform.
 
 Fixes:
 
 - Fix event parsing for PMUs starting with the same prefix.
 
 - Fix the 'perf trace' 'trace' alias installation dir.
 
 - Fix buffer size to report iregs in perf script python scripts, supporting
   the extended registers in PowerPC.
 
 - Fix overflow in elf_sec__is_text().
 
 - Fix 's' on source line when disasm is empty in the annotation TUI, accessible
   via 'perf annotate', 'perf report' and 'perf top'.
 
 - Plug leaks in scandir() returned dirent entries in 'perf test' when sorting
   the shell tests.
 
 - Fix --task and --stat with pipe input in 'perf report'.
 
 - Fix 'perf probe' use of debuginfo files by build id.
 
 - If a DSO has both dynsym and symtab ELF sections, read from both when loading
   the symbol table, fixing a problem processing Fedora 32 glibc DSOs.
 
 Libraries:
 
 - Add grouping of events to libperf, from code in tools/perf, allowing
   libperf users to use that mode.
 
 Misc:
 
 - Filter plt stubs from the 'perf probe --functions' output.
 
 - Update UAPI header copies for asound, DRM, mman-common.h and the ones
   affected by the quotactl_fd syscall.
