[POWERPC] Remove fixup_bigphys_addr() for arch/powerpc to avoid link error
There are no actual implementations of fixup_bigphys_addr() in arch/powerpc, and with a 64-bit aware ioremap() and so forth, it should no longer be necessary. This patch removes the last dregs of fixup_bigphys_addr() from arch/powerpc. In fact, the only reason this hasn't caused link errors already is that nobody must have tried using one of the small number of drivers using io_remap_pfn_range() on one of the small number of platforms which are 32-bit but define CONFIG_PHYS_64BIT. Nonetheless this fixes a bug, and should go into 2.6.22. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
