From 3381959da5a00ae8289cfbd28b0b6d228f2d1d46 Mon Sep 17 00:00:00 2001 From: Alok Kataria Date: Tue, 24 Jun 2008 11:48:30 -0700 Subject: x86: cleanup e820_setup_gap(), add e820_search_gap(), v2 This is a preparatory patch for the next patch in series. Moves some code from e820_setup_gap to a new function e820_search_gap. This patch is a part of a bug fix where we walk the ACPI table to calculate a gap for PCI optional devices. v1->v2: Patch on top of tip/master. Fixes a bug introduced in the last patch about the typeof "last". Also the new function e820_search_gap now returns if we found a gap in e820_map.
