From a491503e4d0cb739f409069826e2746e38826099 Mon Sep 17 00:00:00 2001 From: Alexander van Heukelum Date: Fri, 26 Sep 2008 14:03:06 +0200 Subject: [PATCH] traps: x86_64: remove trace_hardirqs_fixup from debug handler All exceptions are taken via interrupt gates. TRACE_IRQS_OFF is called just before entering the C code, so the irq state is known to the irq tracer at this point. No need to call trace_hardirqs_fixup.
