Subject: [Patchv5 1/7] KVM: s390: add and extend interrupt information data structs
Date: Tue,  8 Oct 2013 16:54:54 +0200	[thread overview]
Message-ID: <1381244100-59056-2-git-send-email-borntraeger@de.ibm.com> (raw)
In-Reply-To: <1381244100-59056-1-git-send-email-borntraeger@de.ibm.com>

From: Jens Freimann <jfrei@linux.vnet.ibm.com>

With the currently available struct kvm_s390_interrupt it is not possible to
inject every kind of interrupt as defined in the z/Architecture. Add
additional interruption parameters to the structures and move it to kvm.h
