Subject: [PATCH 0/4] MIPS cache & highmem fixes

This series fixes up a few issues with our current cache maintenance
code, some specific to highmem & some not. It fixes an issue with icache
corruption seen on the pistachio SoC & Ci40, and icache corruption seen
using highmem on MIPS Malta boards with a P5600 CPU.

Applies atop v4.5-rc6. It would be great to squeeze these in for v4.5,
but I recognise it's quite late in the cycle & this brokenness has been
around for a while so won't object to v4.6.

Thanks,
    Paul

  MIPS: Flush dcache for flush_kernel_dcache_page
  MIPS: Flush highmem pages in __flush_dcache_page
  MIPS: Handle highmem pages in __update_cache
  MIPS: Sync icache & dcache in set_pte_at
