From f7185bf731efd1015821f4153ac17d653dbd23c9 Mon Sep 17 00:00:00 2001
From: Andrew Pinski <apinski@cavium.com>
Date: Wed, 3 Sep 2014 14:19:02 -0700
Subject: [PATCH 08/25] Allow a 32bit ABI to use the naming of the 64bit ABI
syscalls to avoid confusion of not splitting the registers
In the ARM64 ILP32 case, we want to say the syscalls that normally would pass
64bit as two arguments are now passing as one so want to use the 64bit
naming scheme.
