    mm: don't use alloc_bootmem_low() where not strictly needed · 3c1596ef

    Since alloc_bootmem() will never return inaccessible (via virtual
    addressing) memory anyway, using the ..._low() variant only makes sense
    when the physical address range of the allocated memory must fulfill
    further constraints, espacially since on 64-bits (or more generally in all
    cases where the pools the two variants allocate from are than the full
    available range.
    Probably the use in alloc_tce_table() could also be eliminated (based on
    code inspection of pci-calgary_64.c), but that seems too risky given I
    know nothing about that hardware and have no way to test it.
