Date: Fri, 26 Sep 2008 14:03:03 +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 2/7] traps: x86_64: add TRACE_IRQS_OFF in paranoidentry macro Add TRACE_IRQS_OFF just before entering the C code. All exceptions are taken via interrupt gates. If irq tracing is enabled, it should be notified as soon as possible. Interrupts are only (conditionally) re-enabled in C code.
