From: "H. Peter Anvin" <hpa@linux.intel.com>
This patch series generates all the files that depend on the x86
system call numbers -- specifically unistd_*.h and the system call
tables themselves -- from a simple text file table. Furthermore, it
unifies the multiple different ways that the system call tables are
generated. Although this is an x86-specific patch, the scripts are
intended to be generic enough that it should be easy for other
architectures to use them as well.
The "ABI" column in the text file is currently unused, however, it is
intended to support the new x32 ABI, and may be helpful for other
architectures that have multiple system call ABI ranges as well.
Special thanks to David Woodhouse, Michal Marek and Sam Ravnborg for
helping me straight out the maze of Kbuild dependencies.

Generated asm headers are supposed to live in
arch/*/include/generated/asm, but objhdr-y expect them to live in the
same directory they are generated in. Instead of trying to cut that
particular Gordian knot, introduce genhdr-y that takes this into
account; the sole user of objhdr-y, linux/version.h, should be
migrated over at some later date.

Add support for an "archheaders" target. This target can generate
files that need to be installed for user space by "make
headers_install" or "make headers_install_all".
In order to support "make headers_install_all", it must be able to run
without the tree having to be configured first.

Adjust spacing for comment so that it matches the multiline comment
style used in the rest of the kernel, and remove word duplication.
It is not really clear what version of gcc this refers to, but the
extra & doesn't cause any harm, so there is no reason to remove it.

Move compat_ni_syscall out of ia32entry.S and into its own .c file.
Although this is a trivial function, it is not performance-critical,
and this will simplify further cleanups.

From: "H. Peter Anvin" <hpa@linux.intel.com>
Generate system call tables and unistd_*.h automatically from the
tables in arch/x86/syscalls. All other information, like NR_syscalls,
is auto-generated, some of which is in asm-offsets_*.c.
This allows us to keep all the system call information in one place,
and allows for kernel space and user space to see different
information; this is currently used for the ia32 system call numbers
when building the 64-bit kernel, but will be used by the x32 ABI in
the near future.
This also removes some gratuitious differences between i386, x86-64
and ia32; in particular, now all system call tables are generated with
the same mechanism.

(Of course, there are architectures on which the syscall set isn't a
dense set of numbers in the range [0, NR_syscalls), but that's another
issue entirely.)

I think you can remove in_list() and just use grep to get your
selected abis:
my_abis=`echo "($3)" | tr ',' '|'`

And finally this becomes:

done

You mean:

x86: Simplify syscallhdr.sh
Simplify syscallhdr.sh by letting grep sort out the ABIs that we want,
rather than relying on manual list matching. This is safe since the
ABI strings already have to consist only of characters which are valid in C
macro names.

x86, syscall: Allow syscall offset to be symbolic
Allow the specified syscall offset to be symbolic, e.g. a macro. For
offset system calls, this if nothing else makes the generated code
easier to read.

I don't think we need the explicit make archheaders call here, it's
handled by the __headers dependency above.

We don't need to explicitly invoke the archheaders target because of
