Subject: [RFC/PATCH] i386: handle all exceptions with interrupts off initially
Date: Tuesday, September 9, 2008 - 3:55 pm

From: Alexander van Heukelum <heukelum@fastmail.fm>

x86_64 handles all exceptions with interrupts off initially, this
bisectable patch set does the same for i386, in (very) small steps.
If this is acceptable, it would make further unification of traps_32.c
and traps_64.c a lot easier. If it is not... why?

Patches are against current -git.

Every step in the series runs fine in a simple system under qemu.

Greetings,
	Alexander
