From 2841029393fad551b49b6de34d44bfa9ef256441 Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 11 Jan 2016 17:15:58 +0000 Subject: ARM: make virt_to_idmap() return unsigned long Make virt_to_idmap() return an unsigned long rather than phys_addr_t. Returning phys_addr_t here makes no sense, because the definition of virt_to_idmap() is that it shall return a physical address which maps identically with the virtual address. Since virtual addresses are limited to 32-bit, identity mapped physical addresses are as well. Almost all users already had an implicit narrowing cast to unsigned long so let's make this official and part of this interface.
