From: Andy Lutomirski <luto@xxxxxxxxxx>
Subject: input: redefine INPUT_COMPAT_TEST as in_compat_syscall()
The input compat code should work like all other compat code: for 32-bit
syscalls, use the 32-bit ABI and for 64-bit syscalls, use the 64-bit ABI.
We have a helper for that (in_compat_syscall()): just use it.
