From ccdcef72c249c289898b164eada89a61855b9287 Mon Sep 17 00:00:00 2001 From: Dale Farnsworth Date: Wed, 17 Dec 2008 10:09:13 +0000 Subject: powerpc/32: Add the ability for a classic ppc kernel to be loaded at 32M Add the ability for a classic ppc kernel to be loaded at an address of 32MB. This done by fixing a few places that assume we are loaded at address 0, and by changing several uses of KERNELBASE to use PAGE_OFFSET, instead.
