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

Pull Sparc bugfixes from David Miller:
 "Four bug fixes:

   1) Enable snoop tags properly on Sparc32/LEON, from Andreas Larsson

   2) strcpy() length check fix from Chen Gang.

   3) Forgotten unregister_netdev() in sunvnet driver, from Dave
      Kleikamp.

   4) Fix broken assembler offsets used in vm_area_struct accesses on
      sparc32, from Olivier DANET."

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
  [PATCH] sparc32: vm_area_struct access for old Sun SPARCs.
  sunvnet: vnet_port_remove must call unregister_netdev
  sparc32, leon: Require separate snoop tags set to regard snooping to be enabled
  arch: sparc: kernel: check the memory length before use strcpy().
