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

Pull MIPS fixes from Ralf Baechle:
 "A round of 4.8 fixes:

  MIPS generic code:
   - Add a missing ".set pop" in an early commit
   - Fix memory regions reaching top of physical
   - MAAR: Fix address alignment
   - vDSO: Fix Malta EVA mapping to vDSO page structs
   - uprobes: fix incorrect uprobe brk handling
   - uprobes: select HAVE_REGS_AND_STACK_ACCESS_API
   - Avoid a BUG warning during PR_SET_FP_MODE prctl
   - SMP: Fix possibility of deadlock when bringing CPUs online
   - R6: Remove compact branch policy Kconfig entries
   - Fix size calc when avoiding IPIs for small icache flushes
   - Fix pre-r6 emulation FPU initialisation
   - Fix delay slot emulation count in debugfs

  ATH79:
   - Fix test for error return of clk_register_fixed_factor.

  Octeon:
   - Fix kernel header to work for VDSO build.
   - Fix initialization of platform device probing.

  paravirt:
   - Fix undefined reference to smp_bootstrap"
