perf s390: Generate system call table from asm/unistd.h
This should speed up accessing new system calls introduced with
the kernel rather than waiting for libaudit updates to include
them.
Committer testing:
$ rm -rf /tmp/build/perf
$ mkdir /tmp/build/perf
$ make srctree=/home/acme/git/perf -C tools/perf/arch/s390 OUTPUT=/tmp/build/perf/ archheaders
make: Entering directory '/home/acme/git/perf/tools/perf/arch/s390'
/bin/sh '/home/acme/git/perf/tools/perf/arch/s390/entry/syscalls//mksyscalltbl' 'cc' /home/acme/git/perf/tools/arch/s390/include/uapi/asm/unistd.h > /tmp/build/perf/arch/s390/include/generated/asm/syscalls_64.c
make: Leaving directory '/home/acme/git/perf/tools/perf/arch/s390'
$ head -5 /tmp/build/perf/arch/s390/include/generated/asm/syscalls_64.c
static const char *syscalltbl_s390_64[] = {
[1] = "exit",
[2] = "fork",
[3] = "read",
[4] = "write",
$ tail -5 /tmp/build/perf/arch/s390/include/generated/asm/syscalls_64.c
[378] = "s390_guarded_storage",
[379] = "statx",
[380] = "s390_sthyi",
};
#define SYSCALLTBL_S390_64_MAX_ID 380
$
Now to plug this into 'perf trace' proper.
