From cab3f16febeaf1a60e38159ff578f609f9976544 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 29 Nov 2005 13:59:03 -0800 Subject: [PATCH] [SPARC64]: Fix >8K I/O mappings. Increment the PFN field of the PTE so that the tests on vm_pfn in mm/memory.c match up. The TLB ignores these lower bits for larger page sizes, so it's OK to set things like this.
