    mips: Use memblock to reserve the __nosave memory range · 4e50a35d
    Serge Semin authored
    Originally before legacy bootmem was removed, the memory for the range was
    correctly reserved by reserve_bootmem_region(). But since memblock has been
    selected for early memory allocation the function can be utilized only
    after paging is fully initialized (as it is done by memblock_free_all()
    function). So calling it from arch_mem_init() method is prone to errors,
    and at this stage we need to reserve the memory in the memblock allocator.
