From: Yinghai Lu Date: Mon, 16 Jun 2008 01:58:51 +0000 (-0700) Subject: x86: rename two e820 related functions X-Git-Tag: v2.6.27-rc1~1106^2~247^2~17 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d0be6bdea103b8d04c8a3495538b7c0011ae4129;p=linux-2.6 x86: rename two e820 related functions rename update_memory_range to e820_update_range rename add_memory_region to e820_add_region to make it more clear that they are about e820 map operations.
