From 14c89e7fc84ae55354b8bf12fee1b6d14f259c8a Mon Sep 17 00:00:00 2001 From: David Gibson Date: Wed, 14 Dec 2005 16:08:40 +1100 Subject: [PATCH] powerpc: Replace VMALLOCBASE with VMALLOC_START On ppc64, we independently define VMALLOCBASE and VMALLOC_START to be the same thing: the start of the vmalloc() area at 0xd000000000000000. VMALLOC_START is used much more widely, including in generic code, so this patch gets rid of the extraneous VMALLOCBASE. This does require moving the definitions of region IDs from page_64.h to pgtable.h, but they don't clearly belong in the former rather than the latter, anyway. While we're moving them, clean up the definitions of the REGION_IDs: - Abolish REGION_SIZE, it was only used once, to define REGION_MASK anyway - Define the specific region ids in terms of the REGION_ID() macro. - Define KERNEL_REGION_ID in terms of PAGE_OFFSET rather than KERNELBASE. It amounts to the same thing, but conceptually this is about the region of the linear mapping (which starts at PAGE_OFFSET) rather than of the kernel text itself (which is at KERNELBASE).
