From b6b7922fbda63040946cac8251d5618ee7880e8a Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sat, 9 Aug 2008 16:25:26 -0700 Subject: sparc64: Don't MAGIC_SYSRQ ifdef smp_fetch_global_regs and support code. Based upon a report and initial patch by Friedrich Oslage. The intention is to provide this facility for __trigger_all_cpu_backtrace even if MAGIC_SYSRQ is not set. The only part that should have MAGIC_SYSRQ ifdef protection is the sparc_globalreg_op sysrq regitration and immediate code. Signed-off-by: David S.
