Date: Fri, 26 Sep 2008 14:03:06 +0200 From: Alexander van Heukelum <heukelum@...tmail.fm> To: Ingo Molnar <mingo@...e.hu>, lkml <linux-kernel@...r.kernel.org> Cc: Alexander van Heukelum <heukelum@...tmail.fm> Subject: [PATCH 5/7] 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.
