Subject: [PATCH 2/2] s390: add Linux banner to the compressed image
Date: Fri, 12 Jul 2019 19:21:01 +0200 [thread overview]
Message-ID: <aa477dd145aa2beb37fe813619b0723744a22a0a.1562950641.git.ptesarik@suse.com> (raw)
In-Reply-To: <cover.1562950641.git.ptesarik@suse.com>
Various tools determine the kernel version from a given binary by
scanning for the Linux banner string. This does not work if the
banner string is compressed, but we can link it once more into the
uncompressed portion of bzImage.
