Jonathan Neuschäfer 2bbf63264a powerpc/mm/32: Use page_is_ram to check for RAM ... On systems where there is MMIO space between different blocks of RAM in the physical address space, __ioremap_caller did not allow mapping these MMIO areas, because they were below the end RAM and thus considered RAM as well. Use the memblock-based page_is_ram function, which returns false for such MMIO holes. v2: Keep the check for p < virt_to_phys(high_memory). On 32-bit systems with high memory (memory above physical address 4GiB), the high memory is expected to be available though ioremap. The high_memory variable marks the end of low memory; comparing against it means that only ioremap requests for low RAM will be denied. Reported by Michael Ellerman.
