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.
