From 6a9b490d5fd7f23c5bcd75f970e01633ad3136e3 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 19 Sep 2005 20:11:57 -0700 Subject: [SPARC64]: Move DCACHE_ALIASING_POSSIBLE define to asm/page.h This showed that arch/sparc64/kernel/ptrace.c was not getting the define properly, and thus the code protected by this ifdef was never actually compiled before. So fix that too. Signed-off-by: David S.
