[PATCH v4 00/45] Use hugepages to map kernel mem on 8xx

The main purpose of this big series is to: - reorganise huge page handling to avoid using mm_slices. - use huge pages to map kernel memory on the 8xx. The 8xx supports 4 page sizes: 4k, 16k, 512k and 8M. It uses 2 Level page tables, PGD having 1024 entries, each entry covering 4M address space. Th
