    tools include UAPI: Sync x86's syscalls_64.tbl and generic unistd.h to pick up clone3 and pidfd_open
    
      05a70a8e ("unistd: protect clone3 via __ARCH_WANT_SYS_CLONE3")
      8f3220a8 ("arch: wire-up clone3() syscall")
      7615d9e1 ("arch: wire-up pidfd_open()")
    
    Silencing the following tools/perf build warnings
    
      Warning: Kernel ABI header at 'tools/include/uapi/asm-generic/unistd.h' differs from latest version at 'include/uapi/asm-generic/unistd.h'
      diff -u tools/include/uapi/asm-generic/unistd.h include/uapi/asm-generic/unistd.h
      Warning: Kernel ABI header at 'tools/perf/arch/x86/entry/syscalls/syscall_64.tbl' differs from latest version at 'arch/x86/entry/syscalls/syscall_64.tbl'
      diff -u tools/perf/arch/x86/entry/syscalls/syscall_64.tbl arch/x86/entry/syscalls/syscall_64.tbl
    
    Now 'perf trace -e pidfd*,clone*' will trace those syscalls as well as the
    others with those prefixes.
