From 8f20b20de73eeabe3d35e67e0ce993eceef07492 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Thu, 11 Sep 2008 23:19:22 -0700 Subject: [PATCH] sparc64: Fix sparse warnings in global reg snapshotting. Lots of shadowed local variables and global_reg_snapshot[] needs an extern declaration in asm/ptrace_64.h. Signed-off-by: David S.
