module: handle ppc64 relocating kcrctabs when CONFIG_RELOCATABLE=y
powerpc applies relocations to the kcrctab. They're absolute symbols, but it's not completely unreasonable: other archs may too, but the relocation is often 0. http://lists.ozlabs.org/pipermail/linuxppc-dev/2009-November/077972.html Inspired-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Tested-by: Neil Horman <nhorman@tuxdriver.com> Acked-by: Paul Mackerras <paulus@samba.org>
