Vineet Gupta	d9820ff76f	ARC: mm: switch pgtable_t back to struct page * ... So far ARC pgtable_t has not been struct page based to avoid extra page_address() calls involved. However the differences are down to noise and get in the way of using generic code, hence this patch. This also allows us to reuse generic THP depost/withdraw code. There's some additional consideration for PGDIR_SHIFT in 4K page config. Now due to page tables being PAGE_SIZE deep only, the address split can't be really arbitrary.

Vineet Gupta	fe6cb7b043	ARC: mm: disintegrate pgtable.h into levels and flags ... - pgtable-bits-arcv2.h (MMU specific page table flags) - pgtable-levels.h (paging levels) No functional changes, but paves way for easy addition of new MMU code with different bits and levels etc Signed-off-by: Vineet Gupta <vgupta@kernel.org>	2021-08-25 15:53:19 -07:00
