Date: Sun, 8 May 2011 13:51:22 +0100 From: Catalin Marinas <catalin.marinas@....com> To: linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org Cc: Russell King - ARM Linux <linux@....linux.org.uk> Subject: [PATCH v5 03/19] ARM: LPAE: Use unsigned long for __phys_to_virt and __virt_to_phys The !CONFIG_ARM_PATCH_PHYS_VIRT case uses macros for __phys_to_virt and __virt_to_phys but does not use any type casting. This causes issues with LPAE where the phys_addr_t is 64-bit. Note that these macros are only valid for lowmem physical addresses where the range is within 32-bit.
