From 6650239a4b01077e80d5a4468562756d77afaa59 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sat, 8 Jan 2011 17:45:38 -0500 Subject: NFS: Don't use vm_map_ram() in readdir vm_map_ram() is not available on NOMMU platforms, and causes trouble on incoherrent architectures such as ARM when we access the page data through both the direct and the virtual mapping. The alternative is to use the direct mapping to access page data for the case when we are not crossing a page boundary, but to copy the data into a linear scratch buffer when we are accessing data that spans page boundaries.
