Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS fixes from Ralf Baechle:
- Three highmem fixes:
+ Fixed mapping initialization
+ Adjust the pkmap location
+ Ensure we use at most one page for PTEs
- Fix makefile dependencies for .its targets to depend on vmlinux
- Fix reversed condition in BNEZC and JIALC software branch emulation
- Only flush initialized flush_insn_slot to avoid NULL pointer
dereference
- perf: Remove incorrect odd/even counter handling for I6400
- ftrace: Fix init functions tracing
