From: Alexander van Heukelum Date: Fri, 26 Sep 2008 12:03:03 +0000 (+0200) Subject: traps: x86_64: add TRACE_IRQS_OFF in paranoidentry macro X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7e61a7932495e37685e95ec9a59ad08810dec959;p=linux-beck.git 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.
