From 979fe44af819d76fc02a5a97ad1cb74f7d83578e Mon Sep 17 00:00:00 2001 From: Alexander Gordeev Date: Wed, 16 Aug 2023 15:29:42 +0200 Subject: s390/ipl: fix virtual vs physical address confusion The value of ipl_cert_list_addr boot variable contains a physical address, which is used directly. That works because virtual and physical address spaces are currently the same, but otherwise it is wrong. While at it, fix also a comment for the platform keyring.
