From 2c419bdeca1d958bb02228b5141695f312d8c633 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Wed, 23 Apr 2008 23:05:20 +1000 Subject: [POWERPC] Port fixmap from x86 and use for kmap_atomic The fixmap code from x86 allows us to have compile time virtual addresses that we change the physical addresses of at run time. This is useful for applications like kmap_atomic, PCI config that is done via direct memory map, kexec/kdump. We got ride of CONFIG_HIGHMEM_START as we can now determine a more optimal location for PKMAP_BASE based on where the fixmap addresses start and working back from there. Additionally, the kmap code in asm-powerpc/highmem.h always had debug enabled. Moved to using CONFIG_DEBUG_HIGHMEM to determine if we should have the extra debug checking.
