      sh: Support for extended ASIDs on PTEAEX-capable SH-X3 cores. · 8263a67e
      Paul Mundt 提交于
      This adds support for extended ASIDs (up to 16-bits) on newer SH-X3 cores
      that implement the PTAEX register and respective functionality. Presently
      only the 65nm SH7786 (90nm only supports legacy 8-bit ASIDs).
      
      The main change is in how the PTE is written out when loading the entry
      in to the TLB, as well as in how the TLB entry is selectively flushed.
      
      While SH-X2 extended mode splits out the memory-mapped U and I-TLB data
      arrays for extra bits, extended ASID mode splits out the address arrays.
      While we don't use the memory-mapped data array access, the address
      array accesses are necessary for selective TLB flushes, so these are
      implemented newly and replace the generic SH-4 implementation.
      
      With this, TLB flushes in switch_mm() are almost non-existent on newer
      parts.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
