From 640768eef245f1578e75e02c17d277a1496a535b Mon Sep 17 00:00:00 2001 From: Stephen Rothwell Date: Fri, 28 Oct 2005 12:51:45 +1000 Subject: [PATCH] ppc64: use the merged syscall table This allows us to also use entry_64.S from the merged tree and reverts the setup_64.c part of fda262b8978d0089758ef9444508434c74113a61.
