Merge branch 'next-devicetree' of git://git.secretlab.ca/git/linux-2.6 

* 'next-devicetree' of git://git.secretlab.ca/git/linux-2.6: (41 commits)
  of: remove undefined request_OF_resource & release_OF_resource
  of/sparc: Remove sparc-local declaration of allnodes and devtree_lock
  of: move definition of of_chosen into common code.
  of: remove unused extern reference to devtree_lock
  of: put default string compare and #a/s-cell values into common header
  of/flattree: Don't assume HAVE_LMB
  of: protect linux/of.h with CONFIG_OF
  proc_devtree: fix THIS_MODULE without module.h
  of: Remove old and misplaced function declarations
  of/flattree: Make the kernel accept ePAPR style phandle information
  of/flattree: endian-convert members of boot_param_header
  of: assume big-endian properties, adding conversions where necessary
  of: use __be32 for cell value accessors
  of/flattree: use OF_ROOT_NODE_{SIZE,ADDR}_CELLS DEFAULT for fdt parsing
  of/flattree: use callback to setup initrd from /chosen
  proc_devtree: include linux/of.h
  of: make set_node_proc_entry private to proc_devtree.c
  of: include linux/proc_fs.h
  of/flattree: merge early_init_dt_scan_memory() common code
  of: add 'of_' prefix to machine_is_compatible()
