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

Pull MIPS updates from Ralf Baechle:
 "A fair number of fixes all across arch/mips.  Nothing really stands
  out though APRP, the FPU code and syscall tracing code received
  multiple patches those all were small"

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
  MIPS: mark O32+FP64 experimental for now
  MIPS: ftrace: Fix icache flush range error
  MIPS: Fix syscall tracing interface
  MIPS: asm: syscall: Fix copying system call arguments
  MIPS: Octeon: Fix fall through on bar type OCTEON_DMA_BAR_TYPE_SMALL
  MIPS: FPU: Fix conflict of register usage
  MIPS: Replace CONFIG_MIPS64 and CONFIG_MIPS32_R2
  MIPS: math-emu: Fix prefx detection and COP1X function field definition
  MIPS: APRP: Choose the correct VPE loader by fixing the linking
  MIPS: APRP: Unregister rtlx interrupt hook at module exit
  MIPS: APRP: Fix the linking of rtlx interrupt hook
  MIPS: bcm47xx: Include missing errno.h for ENXIO
  MIPS: Alchemy: Fix unchecked kstrtoul return value
  MIPS: Fix randconfig build error.
