mainlining shenanigans

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.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
