tools headers UAPI: Sync files changed by the memfd_secret new syscall
To pick the changes in this cset:
7bb7f2ac24a028b2 ("arch, mm: wire up memfd_secret system call where relevant")
That silences these perf build warnings and add support for those new
syscalls in tools such as 'perf trace'.
For instance, this is now possible:
# 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 these perf build warnings:
