      [MIPS] Fixup migration to GENERIC_TIME · 16b7b2ac
      Atsushi Nemoto authored
      Since we already moved to GENERIC_TIME, we should implement alternatives
      of old do_gettimeoffset routines to get sub-jiffies resolution from
      gettimeofday().  This patch includes:
      
       * MIPS clocksource support (based on works by Manish Lachwani).
       * remove unused gettimeoffset routines and related codes.
       * remove unised 64bit do_div64_32().
       * simplify mips_hpt_init. (no argument needed, __init tag)
       * simplify c0_hpt_timer_init. (no need to write to c0_count)
       * remove some hpt_init routines.
       * mips_hpt_mask variable to specify bitmask of hpt value.
       * convert jmr3927_do_gettimeoffset to jmr3927_hpt_read.
       * convert ip27_do_gettimeoffset to ip27_hpt_read.
       * convert bcm1480_do_gettimeoffset to bcm1480_hpt_read.
       * simplify sb1250 hpt functions. (no need to subtract and shift)

      [MIPS] Sibyte: Fix race in sb1250_gettimeoffset(). · a904f747

      From Dave Johnson <djohnson+linuxmips@sw.starentnetworks.com>:
          
      sb1250_gettimeoffset() simply reads the current cpu 0 timer remaining
      value, however once this counter reaches 0 and the interrupt is raised,
      it immediately resets and begins to count down again.
          
      If sb1250_gettimeoffset() is called on cpu 1 via do_gettimeofday() after
      the timer has reset but prior to cpu 0 processing the interrupt and
      taking write_seqlock() in timer_interrupt() it will return a full value
      (or close to it) causing time to jump backwards 1ms. Once cpu 0 handles
      the interrupt and timer_interrupt() gets far enough along it will jump
      forward 1ms.
          
      Fix this problem by implementing mips_hpt_*() on sb1250 using a spare
      timer unrelated to the existing periodic interrupt timers. It runs at
      1Mhz with a full 23bit counter.  This eliminated the custom
      do_gettimeoffset() for sb1250 and allowed use of the generic
      fixed_rate_gettimeoffset() using mips_hpt_*() and timerhi/timerlo.

      The timers need to be loaded with 1 less than the desired interval not
      the interval itself.

      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!
