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

Pull MIPS updates from Ralf Baechle:
 - Some minor work bringing the Cobalt MIPS platforms in line with other
   MIPS platforms
 - Make vmlinux.32 and vmlinux.64 build messages less verbose
 - Always register the R4k clocksource when selected, the clock source's
   rating will decide if this or another clock source is actually going
   to be used
 - Drop support for the Cisco (formerly Scientific Atlanta) PowerTV
   platform.  There appears to be nobody left who cares and the USB
   driver went stale while waiting for years to be merged
 - Some cleanup of Loongson 2 related #ifdefery
 - Various minor cleanups
 - Major rework on all things related to tracing / ptrace on MIPS,
   including switching the MIPS ELF core dumper to regsets, enabling the
   entries for SIGSYS in struct siginfo for MIPS, enabling ftrace
   syscall trace points
 - Some more work to bring DECstation support code in line with other
   more modern code
 - Report the name of the detected CPU, not just its CP0 PrID value
 - Some more BCM 47xx and atheros ath79xx work
 - Support for compressed kernels using the XZ compression scheme

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (53 commits)
  MIPS: remove duplicate define
  MIPS: Random whitespace clean-ups
  MIPS: traps: Reformat notify_die invocations to 80 columns.
  MIPS: Print correct PC in trace dump after NMI exception
  MIPS: kernel: cpu-probe: Report CPU id during probe
  MIPS: Remove unused defines in piix4.h
  MIPS: Get rid of hard-coded values for Malta PIIX4 fixups
  MIPS: Always register R4K clock when selected
  MIPS: Loongson: Get rid of Loongson 2 #ifdefery all over arch/mips.
  MIPS: cacheops.h: Increase indentation by one tab.
  MIPS: Remove bogus BUG_ON()
  MIPS: PowerTV: Remove support code.
  MIPS: ftrace: Add support for syscall tracepoints.
  MIPS: ptrace: Switch syscall reporting to tracehook_report_syscall_entry().
  MIPS: Move audit_arch() helper function to __syscall_get_arch().
  MIPS: Enable HAVE_ARCH_TRACEHOOK.
  MIPS: Switch ELF core dumper to use regsets.
  MIPS: Implement task_user_regset_view.
  MIPS: ptrace: Use tracehook helpers.
  MIPS: O32 / 32-bit: Always copy 4 stack arguments.
