From mboxrd@z Thu Jan 1 00:00:00 1970 From: catalin.marinas@arm.com (Catalin Marinas) Date: Mon, 25 Oct 2010 10:01:10 +0100 Subject: [RFC PATCH 17/18] ARM: LPAE: define printk format for physical addresses and page table entries In-Reply-To: <20101025085812.25275.55757.stgit@e102109-lin.cambridge.arm.com> References: <20101025085812.25275.55757.stgit@e102109-lin.cambridge.arm.com> Message-ID: <20101025090109.25275.23930.stgit@e102109-lin.cambridge.arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Will Deacon Now that the Kernel supports 2 level and 3 level page tables, physical addresses (and also page table entries) may be 32 or 64-bits depending upon the configuration. This patch adds a conversion specifier (PHYS_ADDR_FMT) which represents a u32 or u64 depending on the width of a physical address.
