        Remove __set_fixmap_ma and handle difference in installing 
machine-address
        and pseudo-physical-address fixmap entries inside __set_fixmap.
        fixmap.h:
          Remove __set_fixmap_ma and handle difference in installing 
machine-address
          and pseudo-physical-address fixmap entries inside __set_fixmap.
        ioremap.c:
          Change set_fixmap_ma call to set_fixmap call.
        init.c:
          Remove __set_fixmap_ma and handle difference in installing 
machine-address
          and pseudo-physical-address fixmap entries inside __set_fixmap.
          Change __set_fixmap_ma calls to set_fixmap calls and set_fixmap_ma_ro 
call
          to __set_fixmap(,, PAGE_KERNEL_RO) call.
