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

Pull MIPS fixes from Ralf Baechle:
 "Various fixes across the tree.  The modpost error due to
  virt_addr_valid() not being usable from modules required a number of
  preparatory cleanups so a clean fix was possible."

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
  MIPS: 64-bit: Fix build if !CONFIG_MODULES
  MIPS: Wire up finit_module syscall.
  MIPS: Fix modpost error in modules attepting to use virt_addr_valid().
  MIPS: page.h: Remove now unnecessary #ifndef __ASSEMBLY__ wrapper.
  MIPS: Switch remaining assembler PAGE_SIZE users to <asm/asm-offsets.h>.
  MIPS: Include PAGE_S{IZE,HIFT} in <asm/offset.h>.
  MIPS: Don't include <asm/page.h> unnecessarily.
  MIPS: Fix comment.
  Revert "MIPS: Optimise TLB handlers for MIPS32/64 R2 cores."
  MIPS: perf: Fix build failure in XLP perf support.
  MIPS: Alchemy: Make 32kHz and r4k timer coexist peacefully
