perf/urgent fixes:
perf header:
Vince Weaver:
- Fix divide by zero error if f_header.attr_size==0, found using a perf tool fuzzer.
Numfor Mbiziwo-Tiapo:
- Silence use of uninitialized value warning pointed out by clang's MSAN tool.
libbpf:
Andrii Nakryiko:
- Fix missing __WORDSIZE definition in some systems, such as musl libc (Alpine Linux).
tools header UAPI:
Arnaldo Carvalho de Melo:
- Sync headers to address perf build warnings:
- syscalls_64.tbl and generic unistd.h to pick up clone3 and pidfd_open.
- With new ioctls: kvm.h, drm.h and usbdevice_fs.h.
- No tooling change: mman.h, sched.h and if_link.h.
Documentation:
Vince Weaver:
- Fix perf.data documentation units for memory size, its kB, not bytes.
