This series fixes up the generated TLB exception handlers to take into
account cases where there are less fill bits in the Entry{Lo,Hi}
registers than there are software defined bits in a PTE. The most
notable case of this is when running a MIPS32 kernel on a MIPS64 system,
and given that RIXI is required on MIPSr6 support for it is required in
order to run MIPS32 kernels on MIPS64r6 CPUs.

Paul Burton (6):
  MIPS: tlbex: stop open-coding build_convert_pte_to_entrylo
  MIPS: tlbex: remove some RIXI redundancy
  MIPS: tlbex: share MIPS32 32 bit phys & MIPS64 64 bit phys code
  MIPS: tidy EntryLo bit definitions, add PFN
  MIPS: tlbex: avoid placing software PTE bits in Entry* PFN fields
  MIPS: allow RIXI for 32-bit kernels on MIPS64
