Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
"This weeks' round of MIPS bug fixes for 3.18:
- wire up the bpf syscall
- fix TLB dump output for R3000 class TLBs
- fix strnlen_user return value if no NUL character was found.
- fix build with binutils 2.24.51+. While there is no binutils 2.25
release yet, toolchains derived from binutils 2.24.51+ are already
in common use.
- the Octeon GPIO code forgot to offline GPIO IRQs.
- fix build error for XLP.
- fix possible BUG assertion with EVA for CMA"
* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
MIPS: Fix build with binutils 2.24.51+
MIPS: R3000: Fix debug output for Virtual page number
MIPS: Fix strnlen_user() return value in case of overlong strings.
MIPS: CMA: Do not reserve memory if not required
MIPS: Wire up bpf syscall.
MIPS/Xlp: Remove the dead function destroy_irq() to fix build error
MIPS: Octeon: Make Octeon GPIO IRQ chip CPU hotplug-aware
