Subject: [PATCH 00/15] arch: synchronize syscall tables in preparation for y2038
The system call tables have diverged a bit over the years, and a number
of the recent additions never made it into all architectures, for one
reason or another.
This is an attempt to clean it up as far as we can without breaking
compatibility, doing a number of steps:
- Add system calls that have not yet been integrated into all
architectures but that we definitely want there.
- Add the separate ipc syscalls on all architectures that
traditionally only had sys_ipc(). This version is done without
support for IPC_OLD that is we have in sys_ipc. The
new semtimedop_time64 syscall will only be added here, not
in sys_ipc
- Add syscall numbers for a couple of syscalls that we probably
don't need everywhere, in particular pkey_* and rseq,
for the purpose of symmetry: if it's in asm-generic/unistd.h,
it makes sense to have it everywhere.
- Prepare for having the same system call numbers for any future
calls. In combination with the generated tables, this hopefully
makes it easier to add new calls across all architectures
together.
Most of the contents of this series are unrelated to the actual
y2038 work, but for the moment, that second series is based on
this one. If there are any concerns about changes here, I
can drop or rewrite any individual patch in this series.
My plan is to merge any patches in this series that are found
to be good together with the y2038 patches for linux-5.1, so
please review and provide Acks for merging through my tree,
or pick them up for 5.0 if they seem urgent enough.
