While the implementation of the "slices" address space allows a significant amount of high slices, it limits the number of low slices to 16 due to the use of a single u64 low_slices_psize element in struct mm_context_t On the 8xx, the minimum slice size is the size of the area covered by a single PMD entry, ie 4M in 4K pages mode and 64M in 16K pages mode. This means we could have at least 64 slices. In order to override this limitation, this patch switches the handling of low_slices_psize to char array as done already for high_slices_psize.
