Subject: [kvm-unit-tests PATCH v2 1/7] s390x: Cleanup flat.lds
Date: Thu, 12 Jan 2023 15:45:42 +0000	[thread overview]
Message-ID: <20230112154548.163021-2-frankja@linux.ibm.com> (raw)
In-Reply-To: <20230112154548.163021-1-frankja@linux.ibm.com>

It seems like the loader file was copied over from another
architecture which has a different page size (64K) than s390 (4K).

Let's use a 4k alignment instead of the 64k one and remove unneeded
entries.
