From e9e7870f90e3587b712e05db2ded947a3f617119 Mon Sep 17 00:00:00 2001 From: Alexander Egorenkov Date: Tue, 15 Jun 2021 14:25:41 +0200 Subject: s390/dump: introduce boot data 'oldmem_data' The new boot data struct shall replace global variables OLDMEM_BASE and OLDMEM_SIZE. It is initialized in the decompressor and passed to the decompressed kernel. In comparison to the old solution, this one doesn't access data at fixed physical addresses which will become important when the decompressor becomes relocatable.
