Subject: [PATCH 24/35] KVM: PPC: initialize IVORs in addition to IVPR
Date: Tue, 31 Aug 2010 04:32:05 +0200	[thread overview]
Message-ID: <1283221937-21006-25-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1283221937-21006-1-git-send-email-agraf-l3A5Bk7waGM@public.gmane.org>

From: Hollis Blanchard <hollis_blanchard-nmGgyN9QBj3QT0dZR+AlfA@public.gmane.org>

Developers can now tell at a glace the exact type of the premature interrupt,
instead of just knowing that there was some premature interrupt.
