Subject: [PATCH v2 00/13] linux system call fixes

From: Arnd Bergmann <arnd@...db.de>

This is a minor update to v1 of this series. If there are no new
concerns, I would like to send this as a pull request for v6.10-rc6,
which is a little late, but these are all bug fixes. Changes since
v1 are:

 - collect acks
 - minor fixes to the changelog text
 - drop mips patch that was already merged
 - drop the time32 patch that caused build failures
 - fix a kernel/sys_ni.c stub bug that was exposed by
   the compat_sys_io_pgetevents_time64 change

Original series description:

I'm working on cleanup series for Linux system call handling, trying to
unify some of the architecture specific code there among other things.

In the process, I came across a number of bugs that are ABI relevant,
so I'm trying to merge these first. I found all of these by inspection,
not by running the code, so any extra review would help. I assume some
of the issues were already caught by existing LTP tests, while for others
we could add a test. Again, I did not check what is already there.

The sync_file_range and fadvise64_64 changes on sh, csky and hexagon
are likely to also require changes in the libc implementation.

Once the patches are reviewed, I plan to merge my changes as bugfixes
through the asm-generic tree, but architecture maintainers can also
pick them up directly to speed up the bugfix.
