v1: https://www.spinics.net/lists/linux-mm/msg145939.html
This patchset makes it possible to allocate MMIO ranges that are between the two RAM chunks on the Wii, MEM1 and MEM2, not only with ioremap (which previously worked through a hack) but also with kernel/resource.c. Changes in v2: - I added back the p < virt_to_phys(high_memory) check in __ioremap_caller because high memory should be allocatable through ioremap - I expanded the commit messages a bit Jonathan Neuschäfer (5): powerpc: mm: Simplify page_is_ram by using memblock_is_memory powerpc: mm: Use memblock API for PPC32 page_is_ram powerpc/mm/32: Use page_is_ram to check for RAM powerpc: wii: Don't rely on the reserved memory hack powerpc/mm/32: Remove the reserved memory hack arch/powerpc/mm/init_32.c | 5 ----- arch/powerpc/mm/mem.c | 12 +----------- arch/powerpc/mm/mmu_decl.h | 1 - arch/powerpc/mm/pgtable_32.c | 2 +- arch/powerpc/platforms/embedded6xx/wii.c | 14 +------------- 5 files changed, 3 insertions(+), 31 deletions(-) -- 2.16.2
