    x86: memblock: set current limit to max low memory address · 5b6e5295
    Santosh Shilimkar authored
    The memblock current limit value is used to limit early boot memory
    allocations below max low memory address by default, as the kernel can
    access only to the low memory.
    
    Hence, set memblock current limit value to the max mapped low memory
    address instead of max mapped memory address.
