X-Git-Tag: MMI-PSA29.97-13-9~53699^2~16^2 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cab3f16febeaf1a60e38159ff578f609f9976544;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git [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.
