[PATCH 5/7] traps: x86_64: remove trace_hardirqs_fixup from debug handler
From: Alexander van Heukelum
Date: Fri Sep 26 2008 - 08:42:23 EST
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.
