Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

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.
