    Pull MIPS updates from Ralf Baechle:
     "Boston platform support:
       - Document DT bindings
       - Add CLK driver for board clocks
       - Avoid per-core locking with CM3 & higher
       - WARN on attempt to lock invalid VP, not BUG
       - Prevent multi-core with dcache aliasing
       - Handle cores not powering down more gracefully
       - Handle spurious VP starts more gracefully
       - Add lwx & lhx missaligned access support
       - Add MIPS support along with many supporting change to add the
         required infrastructure
      Generic arch code:
       - Misc sysmips MIPS_ATOMIC_SET fixes
       - Drop duplicate HAVE_SYSCALL_TRACEPOINTS
       - Negate error syscall return in trace
       - Correct forced syscall errors
       - Traced negative syscalls should return -ENOSYS
       - Allow samples/bpf/tracex5 to access syscall arguments for sane
       - Cleanup from old Kconfig options in defconfigs
       - Fix PREF instruction usage by memcpy for MIPS R6
       - Fix various special cases in the FPU eulation
       - Fix some special cases in MIPS16e2 support
       - Fix MIPS I ISA /proc/cpuinfo reporting
       - Sort MIPS Kconfig alphabetically
       - Fix minimum alignment requirement of IRQ stack as required by
         ABI / GCC
       - Fix special cases in the module loader
       - Perform post-DMA cache flushes on systems with MAARs
       - Probe the I6500 CPU
       - Cleanup cmpxchg and add support for 1 and 2 byte operations
       - Use queued read/write locks (qrwlock)
       - Use queued spinlocks (qspinlock)
       - Add CPU shared FTLB feature detection
       - Handle tlbex-tlbp race condition
       - Allow storing pgd in C0_CONTEXT for MIPSr6
       - Use current_cpu_type() in m4kc_tlbp_war()
       - Support Boston in the generic kernel
      Generic platform:
       - yamon-dt: Pull YAMON DT shim code out of SEAD-3 board
       - yamon-dt: Support > 256MB of RAM
       - yamon-dt: Use serial* rather than uart* aliases
       - Abstract FDT fixup application
       - Set RTC_ALWAYS_BCD to 0
       - Add a MAINTAINERS entry
      core kernel:
       - qspinlock.c: include linux/prefetch.h
      Loongson 3:
       - Add support
       - Add I6500 support
       - Remove GIC timer from DT
       - Set interrupt-parent per-device, not at root node
       - Fix GIC interrupt specifiers
       - Skip IPI setup if we only have a single CPU
       - Make comment match reality
       - Improvements to time code in VDSO"
