This will be an automated scripts to provide easy support
for add/modify/delete the system call entry by add in
respective *.tbl file.
System call table generation support for asm-generic is
provide for arm64 architecture which will use the common
scripts resides in scripts directory and use syscall.tbl
syscall_arm32.tbl files as inputs. This implementation
will replace asm-generic/unistd.h.
This patch depends on:

1.9.1
Assign the generated values - __NR_C32_Linux_syscalls and
__NR_64_Linux_syscalls instead of __NR_compat_syscalls and
__NR_syscalls respectively. It is better than hard coding
it.
One of the patch in the patch series will generate the
headers and calculate the total number of syscalls that
can be assigned. Otherwise the hard coded values need to
be changed whenever we either add a new system call or
delete a existing system call.

1.9.1
Add Makefile changes to invoke the system call table generation
script which is placed in scripts directory as a common location
accessible for all the architectures.
Add syscall_arm32.tbl in syscalls directory which is copied from
arch/arm/tools/syscall.tbl and made some changes as per the req-
uirement which will be used as input for the scripts which gene-
rate the uapi and kapi headers.

1.9.1
Unified system call table generation script need to be invoked
to generated the uapi and kapi headers. The Makefile changes
present in this patch will invoke the scripts and generate uapi
and kapi header files.
The generated files - unistd_*.h and syscall_table_*.h files
will be included by unistd.h, sys.c and sys32.c files by rep-
lacing asm-generic/unistd.h file.

I'm having a hard time understanding what the benefit of this series is,
given that we only support EABI compat tasks. When adding a new compat
system call, you can't just blindly hook it up without checking whether it
needs a wrapper to deal with any type conversion etc, so really we're just
replacing one table with another as far as I can tell. What am I missing?
I also really don't think we should be generating the 32-bit UAPI headers
from the 64-bit compat system call support (if that's what you're trying to
do -- make headers_check fails with your patches applied). arch/arm/ is the
canonical place for the 32-bit UAPI, and we're just implementing that.

The point that is missing in the description above is that all unistd.h
and syscall.S files are now being generated from a .tbl file, across
all architectures. This was already done on arm32, x86 and s390
before 4.20, but is now done on all architectures that don't use
the uapi/asm-generic/unistd.h header, and the arm32 compat version for
arm64.
The newly added file has the same format as all other tables, and
will be easier to synchronize with the arm32 version, which has
almost the same contents (arm32 has oabi support, arm64 has
compat support).

I think you just misread what Firoz was trying to say here: The
arm64 uapi/asm/unistd.h file is now being generated from the
generic syscall.tbl file, while the compat asm/unistd32.h file is not
part of the UAPI. In both cases though, the data from the old files
is being replaced with data in the more compact and (hopefully)
more readable format.

Hi Arnd, Will,
thanks for the email.
I'm want to abandon this patch series. Will post new patch series for
system call
table generation support for asm-generic and some other stuff together by end of
this week or early next week.
Thanks
Firoz
