From 22d651dcef536c75f75537290bf3da5038e68b6b Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 21 Jan 2014 15:22:17 +1100 Subject: selftests/powerpc: Import Anton's memcpy / copy_tofrom_user tests Turn Anton's memcpy / copy_tofrom_user test into something that can live in tools/testing/selftests. It requires one turd in arch/powerpc/lib/memcpy_64.S, but it's pretty harmless IMHO. We are sailing very close to the wind with the feature macros. We define them to nothing, which currently means we get a few extra nops and include the unaligned calls.
