Subject: [PATCH] anobjrmap 6/6 arches
Date: Thu, 20 Mar 2003 23:17:14 +0000 (GMT) [thread overview]
Message-ID: <Pine.LNX.4.44.0303202316470.2743-100000@localhost.localdomain> (raw)
In-Reply-To: <Pine.LNX.4.44.0303202310440.2743-100000@localhost.localdomain>
anonjrmap 6/6 updates to arches other than i386
Some arches refer to page->mapping for their cache flushing,
generally use page_mapping instead: it appears that they're
coping with shared pagecache issues, rather than anon swap.
Change put_dirty_page(current,,) to put_stack_page(mpnt,,).
No special page table initialization needed for rmap.
Delete pte_addr_t from asm/pgtable.h. Delete asm/rmap.h.
There's some peculiar __users code in asm-s390*/pgtable.h,
looks bogus to me (those counts are included in page_count),
I've just deleted but should confirm with Martin. And a
fix in asm-sh/pgalloc.h: use list_empty on i_mmap_shared.
No i386 files in this patch: but note that with pte_addr_t
gone, its PAE struct page is the same size as without PAE.
