traps: x86_64: add TRACE_IRQS_OFF in error_entry
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. Signed-off-by: Alexander van Heukelum <heukelum@fastmail.fm> Signed-off-by: Ingo Molnar <mingo@elte.hu>
