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: 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().
