      [PATCH] uml: complete hw_controller_type->release conversion · faec1e99
      Paolo 'Blaisorblade' Giarrusso authored
      
      
      This occurrence of free_irq_by_irq_and_dev() was missed when converting UML
      to the use of hw_controller_type->release.

      [PATCH] uml: add and use generic hw_controller_type->release · dbce706e
      Paolo 'Blaisorblade' Giarrusso authored
      
      
      With Chris Wedgwood <cw@f00f.org>
      
      Currently UML must explicitly call the UML-specific
      free_irq_by_irq_and_dev() for each free_irq call it's done.
      
      This is needed because ->shutdown and/or ->disable are only called when the
      last "action" for that irq is removed.
      
      Instead, for UML shared IRQs (UML IRQs are very often, if not always,
      shared), for each dev_id some setup is done, which must be cleared on the
      release of that fd.  For instance, for each open console a new instance
      (i.e.  new dev_id) of the same IRQ is requested().
      
      Exactly, a fd is stored in an array (pollfds), which is after read by a
      host thread and passed to poll().  Each event registered by poll() triggers
      an interrupt.  So, for each free_irq() we must remove the corresponding
      host fd from the table, which we do via this -release() method.
      
      In this patch we add an appropriate hook for this, and remove all uses of
      it by pointing the hook to the said procedure; this is safe to do since the
      said procedure.
      
      Also some cosmetic improvements are included.
      
      This is heavily based on some work by Chris Wedgwood, which however didn't
      get the patch merged for something I'd call a "misunderstanding" (the need
      for this patch wasn't cleanly explained, thus adding the generic hook was
      felt as undesirable).

      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!
