Subject: [PATCH 0/4] syscalls: remove compat_alloc_user_space callers
Date:   Fri, 18 Sep 2020 15:24:35 +0200

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.

I have patches for all other uses of compat_alloc_user_space() as well,
and would expect that we can subsequently remove the interface itself.

Arnd Bergmann (4):
  x86: add __X32_COND_SYSCALL() macro
  kexec: remove compat_sys_kexec_load syscall
  mm: remove compat_sys_move_pages
  mm: remove compat numa syscalls
