From: Arnd Bergmann <arnd@xxxxxxxx>
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.
