[0/4] syscalls: remove compat_alloc_user_space callers

Message

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.
