From fc769a8e70a3348d5de49e5f69f6aff810157360 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 12 Jul 2011 09:58:10 +0200 Subject: [PATCH] memblock: Replace memblock_find_base() with memblock_find_in_range() memblock_find_base() is a static function with two callers in memblock.c and memblock_find_in_range() is a wrapper around it which just changes the types and order of parameters. Make memblock_find_in_range() take phys_addr_t instead of u64 for consistency and replace memblock_find_base() with it.
