* 'next' of git://git.secretlab.ca/git/linux-2.6: (23 commits) powerpc: fix up for mmu_mapin_ram api change powerpc: wii: allow ioremap within the memory hole powerpc: allow ioremap within reserved memory regions wii: use both mem1 and mem2 as ram wii: bootwrapper: add fixup to calc useable mem2 powerpc: gamecube/wii: early debugging using usbgecko powerpc: reserve fixmap entries for early debug powerpc: wii: default config powerpc: wii: platform support powerpc: wii: hollywood interrupt controller support powerpc: broadway processor support powerpc: wii: bootwrapper bits powerpc: wii: device tree powerpc: gamecube: default config powerpc: gamecube: platform support powerpc: gamecube/wii: flipper interrupt controller support powerpc: gamecube/wii: udbg support for usbgecko powerpc: gamecube/wii: do not include PCI support powerpc: gamecube/wii: declare as non-coherent platforms powerpc: gamecube/wii: introduce GAMECUBE_COMMON ... Fix up conflicts in arch/powerpc/mm/fsl_booke_mmu.c. Hopefully even close to correctly.
