Picking up the changes from these csets:
2153b2e891 ("sparc: Add architecture support for clone3")
99d2592023 ("rseq: Implement sys_rseq_slice_yield()")
4ac286c4a8 ("s390/syscalls: Switch to generic system call table generation")
This makes 'perf trace' support it, now its possible, for instance, to
do:
# perf trace -e rseq_slice_yield --max-stack=16
Here is an example with the 'sendmmsg' syscall:
root@x1:~# perf trace -e sendmmsg --max-stack 16 --max-events=1
0.000 ( 0.062 ms): dbus-broker/1012 sendmmsg(fd: 150, mmsg: 0x7ffef57cca50, vlen: 1, flags: DONTWAIT|NOSIGNAL) = 1
syscall_exit_to_user_mode_prepare ([kernel.kallsyms])
syscall_exit_to_user_mode_prepare ([kernel.kallsyms])
syscall_exit_to_user_mode ([kernel.kallsyms])
do_syscall_64 ([kernel.kallsyms])
entry_SYSCALL_64 ([kernel.kallsyms])
[0x117ce7] (/usr/lib64/libc.so.6 (deleted))
root@x1:~#
To do a system wide tracing of the new 'rseq_slice_yield' syscall with a
backtrace of at most 16 entries.
