Kyle HendryandThomas Bogendoerfer 6d5fbecd02 MIPS: mm: Add check for highmem before removing memory block ...

If a device has less physical memory than the highmem threshold
bootmem_init() doesn't set highstart_pfn. This results in highmem_init()
wrongly disabling the entire memory range if the cpu doesn't support
highmem. Add a check that highstart_pfn is non zero before removing the
highmem block.
