    mips: switch to NO_BOOTMEM · bcec54bf
    Mike Rapoport authored
    MIPS already has memblock support and all the memory is already registered
    with it.
    
    This patch replaces bootmem memory reservations with memblock ones and
    removes the bootmem initialization.
    
    Since memblock allocates memory in top-down mode, we ensure that memblock
    limit is max_low_pfn to prevent allocations from the high memory.
    
    To have the exceptions base in the lower 512M of the physical memory, its
    allocation in arch/mips/kernel/traps.c::traps_init() is using bottom-up
    mode.
