To pick the changes in this cset:
7bb7f2ac24 ("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:

Which will probably end up enabling the use of "clone3" in 'perf trace -e',
haven't checked the build with this change on an arm64 system.

Test built it under the ubuntu:14.04.4-x-linaro-arm64 cross build
environment and looked at the syscall table at
/tmp/build/perf/arch/arm64/include/generated/asm/syscalls.c, looks ok.

To get the changes in:
82b355d161 ("y2038: Remove newstat family from default syscall set")
Which will make the syscall table used by 'perf trace' for arm64 to be
updated from the changes in that patch.

Will be used for generating the syscall id/string translation table.
The arm64 unistd.h file simply #includes the asm-generic/unistd.h, so,
since we will want to know whether either change, we grab both:
arch/arm64/include/uapi/asm/unistd.h
and
include/uapi/asm-generic/unistd.h
