      [S390] Reset infrastructure for re-IPL. · 15e9b586
      Heiko Carstens authored
      
      
      In case of re-IPL and diag308 doesn't work we have to reset all devices
      manually and wait synchronously that each reset finished.
      This patch adds the necessary infrastucture and the first exploiter of it.
      
      Subsystems that need to add a function that needs to be called at re-IPL
      may register/unregister this function via
      
      struct reset_call {
      	struct reset_call *next;
      	void (*fn)(void);
      };
      
      void register_reset_call(struct reset_call *reset);
      void unregister_reset_call(struct reset_call *reset);
      
      When the registered function get called the context is:
      
      - all cpus beside the current one are stopped
      - all machine checks and interrupts are disabled
      - prefixing is disabled
      - a default machine check handler is available for use
      
      The registered functions may not take any locks are sleep.
      
      For the common I/O layer part of this patch:
      
      Introduce a reset_call css_reset that does the following:
      - clear all subchannels
      - perform a rchp on all channel paths and wait for the resulting
        machine checks
      This replaces the calls to clear_all_subchannels() and
      cio_reset_channel_paths() for kexec and ccw reipl. reipl_ccw_dev() now
      uses reipl_find_schid() to determine the subchannel id for a given
      device id.
      Also remove cio_reset_channel_paths() and friends since they are not
      needed anymore.

      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!
