From c30bb2a25fcfde6157e6154a32c14686fb0bedbe Mon Sep 17 00:00:00 2001 From: KAMEZAWA Hiroyuki Date: Tue, 22 Sep 2009 16:45:43 -0700 Subject: kcore: add kclist types Presently, kclist_add() only eats start address and size as its arguments. Considering to make kclist dynamically reconfigulable, it's necessary to know which kclists are for System RAM and which are not. This patch add kclist types as KCORE_RAM KCORE_VMALLOC KCORE_TEXT KCORE_OTHER This "type" is used in a patch following this for detecting KCORE_RAM.
