H A D | pgm_check_info.c | 3ca8b855 Sun Aug 11 13:23:56 CDT 2019 Vasily Gorbik <gor@linux.ibm.com> s390/startup: add kaslr_offset to pgm check info print
startup pgm check handler is active since the very beginning of kernel code execution until uncompressed kernel sets up s390_base_pgm_handler.
It is useful not just for the decompressor debugging itself, but also for early code of uncompressed kernel, in particular Kasan initialization. But since there is no stack trace or symbolic representation of failing psw address it is impossible to figure out faulty code location without knowing Kaslr kernel base. So, let's add it to the startup pgm check info printed as well.
