From 9dc5d569c133819c1ce069ebb1d771c62de32580 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Wed, 25 Aug 2010 13:39:15 -0700 Subject: x86, memblock: Add memblock_x86_reserve_range/memblock_x86_free_range They are wrappers for core versions, which take start/end/name instead of base/size. This will make x86 conversion eaasier. could add more debug print out -v2: change get_max_mapped() to memblock.default_alloc_limit according to Michael Ellerman and Ben change to memblock_x86_reserve_range and memblock_x86_free_range according to Michael Ellerman -v3: call check_and_double after reserve/free, so could avoid to use find_memblock_area.
