From: Arnd Bergmann <arnd@arndb.de>
Going through compat_alloc_user_space() to convert indirect system call arguments tends to add complexity compared to handling the native and compat logic in the same code.
There is one other trivial patch I resent for the atomisp staging driver and a longer series for networking ioctls that I need to revalidate before submitting again.
Sorry for the long delay before resending this. Once everyone is happy with the latest version, I would add it to the asm-generic tree for a 5.14 merge.
Arnd ---
Changes in v3:
- fix whitespace as pointed out by Christoph Hellwig - minor build fixes - rebase to v5.13-rc1
Changes in v2:
- address review comments from Christoph Hellwig - split syscall removal into a separate patch - replace __X32_COND_SYSCALL() with individual macros for x32
