Just remind, this is duplicated with patch [1], so you may decide
which one to pick for merging.

Otherwise, LGTM:

Oh, thanks for the reminder.  I've missed it.  I think it's small enough
to merge to perf-tools tree.  I'll drop this part.

[PATCH 11/11] tools headers: Sync syscall table with kernel sources

To pick up changes from:

This should be used to beautify the syscall arguments and it addresses
these tools/perf build warnings:

    diff -u tools/perf/arch/xtensa/entry/syscalls/syscall.tbl arch/xtensa/kernel/syscalls/syscall.tbl

Please see tools/include/README.kernel-copies.

Note that s390 syscall table is still out of sync as it switches to use the
generic table.  But I'd like to minimize the change in this commit.
