5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sven Schnelle <svens@xxxxxxxxxxxxx>
commit ea5717cb13468323a7c3dd394748301802991f39 upstream.
OS installers are relying on /sys/firmware/ipl/has_secure to be
present on machines supporting secure boot. This file is present
for all IPL types, but not the unknown type, which prevents a secure
installation when an LPAR is booted in HMC via FTP(s), because
this is an unknown IPL type in linux. While at it, also add the secure
file.
Fixes: c9896acc7851 ("s390/ipl: Provide has_secure sysfs attribute")
