      [PATCH] s390: spin lock retry · 951f22d5
      Martin Schwidefsky authored
      
      
      Split spin lock and r/w lock implementation into a single try which is done
      inline and an out of line function that repeatedly tries to get the lock
      before doing the cpu_relax().  Add a system control to set the number of
      retries before a cpu is yielded.
      
      The reason for the spin lock retry is that the diagnose 0x44 that is used to
      give up the virtual cpu is quite expensive.  For spin locks that are held only
      for a short period of time the costs of the diagnoses outweights the savings
      for spin locks that are held for a longer timer.  The default retry count is
      1000.

      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!
