From 14778d9072e53d2171f66ffd9657daff41acfaed Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 21 Mar 2006 02:29:39 -0800 Subject: [SPARC]: Respect vm_page_prot in io_remap_page_range(). Make sure the callers do a pgprot_noncached() on vma->vm_page_prot. Pointed out by Hugh Dickens. Signed-off-by: David S.
