From 8b1c870f19849235b8c7e4dfe2ec6b0d691fa9d7 Mon Sep 17 00:00:00 2001 From: Alexander van Heukelum Date: Fri, 26 Sep 2008 14:03:05 +0200 Subject: [PATCH] traps: x86_64: remove trace_hardirqs_fixup from int3 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.
