From 49c3df6aaa6a51071fc135273d1a2515d019099f Mon Sep 17 00:00:00 2001 From: Vivek Goyal Date: Wed, 2 May 2007 19:27:07 +0200 Subject: [PATCH] x86: Move swsusp __pa() dependent code to arch portion o __pa() should be used only on kernel linearly mapped virtual addresses and not on kernel text and data addresses. o Hibernation code needs to determine the physical address associated with kernel symbol to mark a section boundary which contains pages which don't have to be saved and restored during hibernate/resume operation. o Move this piece of code in arch dependent section. So that architectures which don't have kernel text/data mapped into kernel linearly mapped region can come up with their own ways of determining physical addresses associated with a kernel text.
