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

Pull MIPS fixes from Ralf Baechle:
 "Random small fixes across the MIPS code."

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
  MIPS: CMP: Fix physical core number calculation logic
  MIPS: JZ4740: Forward declare struct uart_port in header.
  MIPS: JZ4740: Fix '#include guard' in serial.h
  MIPS: hugetlbfs: Fix hazard between tlb write and pagemask restoration.
  MIPS: Restore pagemask after dumping the TLB.
  MIPS: Hugetlbfs: Handle huge pages correctly in pmd_bad()
  MIPS: R5000: Fix TLB hazard handling.
  MIPS: tlbex: Deal with re-definition of label
  MIPS: Make __{,n,u}delay declarations match definitions and generic delay.h
