From c5dd8586707800cd7bbdefcd675ad7d3c9afcd57 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 5 Mar 2007 23:35:43 +0100 Subject: [S390] reipl: move dump_prefix_page out of text section. Reipl doesn't work on older machines were s390_reset_machine() gets called. The reason is that the text section is read-only but the variable dump_prefix_page is there. Since s390_reset_machine() writes to it we get a protection exception. Therefore move dump_prefix_page to the bss section.
