Hello All,

    powerpc/mm: vmalloc abstraction in preparation for radix

    This commit introduced variables for some linux kernel addresses that had before
    been constants, unfortunately this stopped PaSemi PA6T systems(*) from  booting as
    they call ioremap to map SoC registers before the mmu is initialised. The attached
    patch adds a hard-coded init of pci_io_base to the pas_init_early() function which
    which allows the kernel to boot normally.

    The value will be harmlessly set again once pci starts up.

    (*) At the moment this has only been tested on an AmigaOneX1000, but I expect PaSemi
    reference systems to have been affected in the same way.

Kind regards
Darren

I can't merge this because you didn't sign it off.
