Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

tools UAPI:

  Arnaldo Carvalho de Melo:

  - Sync x86's vmx.h with the kernel.

  - Copy missing unistd.h headers for arc, hexagon and riscv, fixing
    a reported build regression on the ARC 32-bit architecture.

perf bench numa:

  Arnaldo Carvalho de Melo:

  - Add define for RUSAGE_THREAD if not present, fixing the build on the
    ARC architecture when only zlib and libnuma are present.

perf BPF:

  Arnaldo Carvalho de Melo:

  - The disassembler-four-args feature test needs -ldl on distros such as
    Mageia 7.

  Bo YU:

  - Fix unlocking on success in perf_env__find_btf(), detected with
    the coverity tool.

libtraceevent:

  Leo Yan:

  - Change misleading hard coded 'trace-cmd' string in error messages.

ARM hardware tracing:

  Leo Yan:

  - Always allocate memory for cs_etm_queue::prev_packet, fixing a segfault
    when processing CoreSight perf data.

perf annotate:

  Thadeu Lima de Souza Cascardo:

  - Fix build on 32 bit for BPF.

perf report:

  Thomas Richter:

  - Report OOM in status line in the GTK UI.

core libs:

  - Remove needless asm/unistd.h that, used with sys/syscall.h ended
    up redefining the syscalls defines in environments such as the
    ARC arch when using uClibc.
