2018-02-15	perf s390: Rework system call table creation by using syscall.tbl	Hendrik Brueckner	1	-11/+7
	Recently, s390 uses a syscall.tbl input file to generate its system call table and unistd uapi header files. Hence, update mksyscalltbl to use it as input to create the system table for perf.

2017-12-27	perf s390: Generate system call table from asm/unistd.h	Hendrik Brueckner	1	-0/+36
	This should speed up accessing new system calls introduced with the kernel rather than waiting for libaudit updates to include them.
