Date: Tue, 28 Oct 2014 13:44:01 +0800 From: Neil Zhang <zhangwm@...vell.com> To: <linux-arm-kernel@...ts.infradead.org>, <linux-kernel@...r.kernel.org> CC: <catalin.marinas@....com>, <will.deacon@....com>, Neil Zhang <zhangwm@...vell.com> Subject: [PATCH] arm64: ARCH_PFN_OFFSET should be unsigned long pfns are unsigned long, but PHYS_PFN_OFFSET is phys_addr_t. This leads to page_to_pfn() returning phys_addr_t which cause type mismatches in some print statements.
