[Qemu-devel] [PATCH 01/10] s390/ioinst: fix IO_INT_WORD_ISC macro


From: Aurelien Jarno
Subject: [Qemu-devel] [PATCH 01/10] s390/ioinst: fix IO_INT_WORD_ISC macro
Date: Mon, 15 Jun 2015 17:57:00 +0200

The I/O-Interruption Subclass field corresponds to bits 2 to 5 (BE
notation) of the Interruption-Identification Word. The value should
be shift by 27 instead of 24.
