From eee5a9fa63c97366cdea6ab3aa2ed9e3601812d0 Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Fri, 7 Apr 2006 19:49:24 +0200 Subject: [PATCH] x86_64: Rename e820_mapped to e820_any_mapped Rename e820_mapped to e820_any_mapped since it tests if any part of the range is mapped according to the type. Later steps will introduce e820_all_mapped which will check if the entire range is mapped with the type. Both have their merit.
