Mainline only supports 32 byte and 64 byte cache lines on ARM. It does not support 128 byte cache lines, so maybe your attempts are the wrong approach. Can you please post your 128 byte cache line support patches to the ARM kernel mailing list for review.
In the mean time, because your patch causes an oopsing regression, I strongly suggest that it is reverted until we start supporting 128 byte cache lines on ARM in mainline.

ARM926, which has a cache line size of 32.
