Hi Hendrik,
I noticed, after fast forwarding my perf/urgent branch to
torvalds/master, that this appears in my perf build:
Warning: Kernel ABI header at 'tools/arch/s390/include/uapi/asm/unistd.h' differs from latest version at 'arch/s390/include/uapi/asm/unistd.h'
Looking at the log for that file I noticed this cset:
4381f9f12e79 ("s390/syscalls: use generated syscall_table.h and unistd.h header files")
Can you please take a look how this affects the syscall table
generation process in tools/perf and how can we proceed to silence that
warning, i.e. to update the copy we have in tools/?
Thanks,
- Arnaldo

I reworked the our system call table a bit to also have a text file containing
the system calls. For this, I also have an update for perf. Will post these
patches by end of this week.
Thanks and kind regards,
Hendrik
