From 51fae6de24da57bc6cdaa1b253595c3513ecbf2d Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Sun, 4 Dec 2005 18:39:15 +1100 Subject: [PATCH] powerpc: Add a is_kernel_addr() macro There's a bunch of code that compares an address with KERNELBASE to see if it's a "kernel address", ie. >= KERNELBASE. The proper test is actually to compare with PAGE_OFFSET, since we're going to change KERNELBASE soon. So replace all of them with an is_kernel_addr() macro that does that.
