Message-ID: <1352972396-13489-7-git-send-email-tiejun.chen@windriver.com> Date: Thu, 15 Nov 2012 17:39:56 +0800 From: Tiejun Chen <tiejun.chen@...driver.com> To: <benh@...nel.crashing.org> CC: <linuxppc-dev@...ts.ozlabs.org>, <linux-kernel@...r.kernel.org> Subject: [PATCH 6/6] book3e/kexec/kdump: redefine VIRT_PHYS_OFFSET Book3e is always aligned 1GB to create TLB so we should use (KERNELBASE - MEMORY_START) as VIRT_PHYS_OFFSET to get __pa/__va properly while boot kdump.
