From b4c6f400893328d38d03f053d7edaacf9200658e Mon Sep 17 00:00:00 2001 From: Chen Baozi Date: Tue, 7 Apr 2015 19:24:44 +0800 Subject: [PATCH] xen/arm64: Use virtual address when setting up early_printk fixmap We have already switched to the boot pagetable when reaching the point of early_printk fixmap setup. Thus t is no longer necessary to calculate physical address of xen_fixmap.
