Subject: [PATCH 00/10] CPS SMP fixes & debug improvements

This series implements some fixes for the CPS SMP implementation on some
systems, and improves debug by allowing exceptions to be handled &
dumped to an ns16550-compatible UART.

Paul Burton (10):
  MIPS: CPS: set Status.BEV bit during early boot
  MIPS: CPS: set Status.KX on entry for MIPS64 kernels
  MIPS: CPS: early debug using an ns16550-compatible UART
  MIPS: CPS: read CM GCR base from cop0
  MIPS: CPS: skip Config1 presence check
  MIPS: CPS: warn if a core doesn't start
  MIPS: CM: fix GCR_Cx_CONFIG PVPE mask
  MIPS: CM: introduce core-other locking functions
  MIPS: CM: make use of mips_cm_{lock,unlock}_other
  MIPS: CM,CPC: ensure core-other GCRs reflect the correct core
