From 9e2d11b926765681f72db0373d2ecbbac28359b3 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Wed, 2 Jun 2010 10:36:53 +0000 Subject: [PATCH] epic100: Test __BIG_ENDIAN instead of (non-existent) CONFIG_BIG_ENDIAN Probably no one has used this driver on big-endian systems, since it was setting up descriptor swapping if CONFIG_BIG_ENDIAN is set, which it never is, since that symbol is not mentioned anywhere else in the kernel source. Switch this test to a check for __BIG_ENDIAN so it has a chance at working. Signed-off-by: Roland Dreier Acked-by: Jeff Garzik Signed-off-by: David S.
