So, splitted it into three patches and tested the generation, showing the steps and results on the second patch commit message: [acme@jouet perf]$ git log -3 --oneline b91e81b8e967 (HEAD -> perf/core, acme.korg/perf/core) perf trace: Use generated syscall table on s390 too 8fe39fe5058d perf s390: Generate system call table from asm/unistd.h fdd7d74b2782 tools include s390: Grab a copy of arch/s390/include/uapi/asm/unistd.h [acme@jouet perf]$ And pushed it to my perf/core branch on: git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git Please take a look and check that I didn't mess anything up :-) - Arnaldo
