From: Arnd Bergmann <a...@arndb.de> 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.
