SubjectRe: [patch V6 36/37] x86/entry: Move paranoid irq tracing out of ASM code

I think something's missing here. With this patch applied, don't we
get to exc_debug_kernel() -> handle_debug() without doing
idtentry_enter() or equivalent? And that can even enable IRQs.

Maybe exc_debug_kernel() should wrap handle_debug() in some
appropriate _enter() / _exit() pair?
