Subject: Re: [PATCH] avoid ifdefs in desc.h, getting rid of pack_ldt and pack_tss
Date: Thu, 13 Dec 2007 21:58:38 +0100 [thread overview]
Message-ID: <20071213205838.GA9649@elte.hu> (raw)
In-Reply-To: <20071213202800.GD25130@elte.hu>
just got the crash below. config attached. Suspects are:
Subject: unify struct desc_ptr
Subject: unify paravirt pieces of descriptor handling
could we _please_ use basic tools as vmlinux size comparison and
objcompare when unifying, to make sure it's a 100% identity conversion?
