Will Deacon 8e958839e4 sparc32: mm: Restructure sparc32 MMU page-table layout ... The "SRMMU" supports 4k pages using a fixed three-level walk with a 256-entry PGD and 64-entry PMD/PTE levels. In order to fill a page with a 'pgtable_t', the SRMMU code allocates four native PTE tables into a single PTE allocation and similarly for the PMD level, leading to an array of 16 physical pointers in a 'pmd_t' This breaks the generic code which assumes READ_ONCE(*pmd) will be word sized. In a manner similar to ef22d8abd8 ("m68k: mm: Restructure Motorola MMU page-table layout"), this patch implements the native page-table setup directly. This significantly increases the page-table memory overhead, but will be addresses in a subsequent patch. Cc: "David S.
