Subject: [kvm-unit-tests PATCH 5/5] s390x: firq: Fix sclp buffer allocation
Date: Fri, 14 Jan 2022 10:02:45 +0000	[thread overview]
Message-ID: <20220114100245.8643-6-frankja@linux.ibm.com> (raw)
In-Reply-To: <20220114100245.8643-1-frankja@linux.ibm.com>

We need a 32 bit address for the sclp buffer so let's use a page from
the first 31 bits.
