Arnaldo Carvalho de Melo 71a16df164 tools headers UAPI: Sync s390 syscall table file changed by new futex_waitv syscall
To pick the changes in these csets:

  6c122360cf ("s390: wire up sys_futex_waitv system call")

That add support for this new syscall in tools such as 'perf trace'.

For instance, this is now possible (adapted from the x86_64 test output):

  # perf trace -e futex_waitv
  ^C#
  # perf trace -v -e futex_waitv
  event qualifier tracepoint filter: (common_pid != 807333 && common_pid != 3564) && (id == 449)
  ^C#
  # perf trace -v -e futex* --max-events 10
  event qualifier tracepoint filter: (common_pid != 812168 && common_pid != 3564) && (id == 238 || id == 449)
           ? (         ): Timer/219310  ... [continued]: futex())                                            = -1 ETIMEDOUT (Connection timed out)
       0.012 ( 0.002 ms): Timer/219310 futex(uaddr: 0x7fd0b152d3c8, op: WAKE|PRIVATE_FLAG, val: 1)           = 0
       0.024 ( 0.060 ms): Timer/219310 futex(uaddr: 0x7fd0b152d420, op: WAIT_BITSET|PRIVATE_FLAG, utime: 0x7fd0b1657840, val3: MATCH_ANY) = 0
       0.086 ( 0.001 ms): Timer/219310 futex(uaddr: 0x7fd0b152d3c8, op: WAKE|PRIVATE_FLAG, val: 1)           = 0
       0.088 (         ): Timer/219310 futex(uaddr: 0x7fd0b152d424, op: WAIT_BITSET|PRIVATE_FLAG, utime: 0x7fd0b1657840, val3: MATCH_ANY) ...
       0.075 ( 0.005 ms): Web Content/219299 futex(uaddr: 0x7fd0b152d420, op: WAKE|PRIVATE_FLAG, val: 1)     = 1
       0.169 ( 0.004 ms): Web Content/219299 futex(uaddr: 0x7fd0b152d424, op: WAKE|PRIVATE_FLAG, val: 1)     = 1
       0.088 ( 0.089 ms): Timer/219310  ... [continued]: futex())                                            = 0
       0.179 ( 0.001 ms): Timer/219310 futex(uaddr: 0x7fd0b152d3c8, op: WAKE|PRIVATE_FLAG, val: 1)           = 0
       0.181 (         ): Timer/219310 futex(uaddr: 0x7fd0b152d420, op: WAIT_BITSET|PRIVATE_FLAG, utime: 0x7fd0b1657840, val3: MATCH_ANY) ...
  #

That is the filter expression attached to the raw_syscalls:sys_{enter,exit}
tracepoints.

  $ grep futex tools/perf/arch/s390/entry/syscalls/syscall.tbl
  238  common	futex			sys_futex			sys_futex_time32
  422	32	futex_time64		-				sys_futex
  449  common	futex_waitv		sys_futex_waitv			sys_futex_waitv
  $

This addresses this perf build warnings:

  Warning: Kernel ABI header at 'tools/perf/arch/s390/entry/syscalls/syscall.tbl' differs from latest version at 'arch/s390/kernel/syscalls/syscall.tbl'
  diff -u tools/perf/arch/s390/entry/syscalls/syscall.tbl arch/s390/kernel/syscalls/syscall.tbl
