      [MIPS] Rewrite all the assembler interrupt handlers to C. · e4ac58af
      Ralf Baechle 提交于
      Saves like 1,600 lines of code, is way easier to debug, compilers
      frequently do a better job than the cut and paste type of handlers many
      boards had.  And finally having all the stuff done in a single place
      also means alot of bug potencial for the MT ASE is gone.
      
      The only surviving handler in assembler is the DECstation one; I hope
      Maciej will rewrite it.

      [MIPS] Sibyte: Fix race in sb1250_gettimeoffset(). · a904f747
      Ralf Baechle 提交于
          
      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.

      From Dave Johnson <djohnson+linuxmips@sw.starentnetworks.com>:
          
      The timers need to be loaded with 1 less than the desired interval not
      the interval itself.

      [MIPS] SMP: Fix initialization order bug. · 9b6695a8
      Ralf Baechle 提交于
          
      A recent change requires cpu_possible_map to be initialized before
      smp_sched_init() but most MIPS platforms were initializing their
      processors in the prom_prepare_cpus callback of smp_prepare_cpus.  The
      simple fix of calling prom_prepare_cpus from one of the earlier SMP
      initialization hooks doesn't work well either since IPIs may require
      init_IRQ() to have completed, so bit the bullet and split
      prom_prepare_cpus into two initialization functions, plat_smp_setup
      which is called early from setup_arch and plat_prepare_cpus called where
      prom_prepare_cpus used to be called.

      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!
