From 7e61a7932495e37685e95ec9a59ad08810dec959 Mon Sep 17 00:00:00 2001 From: Alexander van Heukelum Date: Fri, 26 Sep 2008 14:03:03 +0200 Subject: 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.
