Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next

Pull sparc updates from David Miller:

 - Automatic system call table generation, from Firoz Khan.

 - Clean up accesses to the OF device names by using full_name instead
   of path_component_name.

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next:
  ALSA: sparc: Use of_node_name_eq for node name comparisons
  sbus: Use of_node_name_eq for node name comparisons
  sparc: generate uapi header and system call table files
  sparc: add system call table generation support
  sparc: add __NR_syscalls along with NR_syscalls
  sparc: move __IGNORE* entries to non uapi header
  sparc: Use DT node full_name instead of name for resources
  sparc: Remove unused leon_trans_init
  sparc: Use device_type helpers to access the node type
  sparc: Use of_node_name_eq for node name comparisons
  sparc: Convert to using %pOFn instead of device_node.name
  sparc: prom: use property "name" directly to construct node names
  of: Drop full path from full_name for PDT systems
  sparc: Convert to using %pOF instead of full_name
  fs/openpromfs: Use of_node_name_eq for node name comparisons
  fs/openpromfs: use full_name instead of path_component_name
