tools headers UAPI: Sync s390 syscall table file that wires up the memfd_secret syscall
To pick the changes in these csets:
7608f70adcb1ea69 ("s390: wire up memfd_secret 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 -v -e memfd_secret
event qualifier tracepoint filter: (common_pid != 13375 && common_pid != 3713) && (id == 447)
^C#
That is the filter expression attached to the raw_syscalls:sys_{enter,exit}
tracepoints.
$ grep memfd_secret tools/perf/arch/x86/entry/syscalls/syscall_64.tbl
447 common memfd_secret sys_memfd_secret
$
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'
