Merge branch 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus

* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus:
  MIPS: Return ENOSYS from sys32_syscall on 64bit kernels like elsewhere.
  MIPS: 64-bit: vmsplice needs to use the compat wrapper for o32 and N32.
  MIPS: o32: Fix number of arguments to splice(2).
  MIPS: Malta: Consolidate platform device code.
  MIPS: IP22, Fulong, Malta: Update defconfigs.
  MIPS: Malta: Add back RTC support
  MIPS: Fix potential DOS by untrusted user app.
