      [PATCH] 2.5.10 IDE 43 · 5ef2759c
      Martin Dalecki authored
      Some of the following is a bit of sensitive... but anyway it has to be done.
      
      - Scarp "portability" macros ide_request_irq() and ide_free_irq().  What a
         great of a surprise in the face of a kernel nowadays ported to nearly any
         major CPU out there, but apparently no platform needs something special here.
         All of them are just using the normal request_irq() and free_irq(). If some
         unusual platform (read obsolete door blocker) I have overlooked intentionally
         needs something special - please just hack the platform specific
         request_irq() and free_irq()-  they are *far off* from being performance
         relevant. (Hint: You could use cooked default irq values to detect there
         whatever the caller was the ATA driver to decide what to do about it.)
      
      - Kill ide_check_region() ide_request_region() and ide_release_region()
         altogether. Add comments explaining the code there.  Same arguments as above
         apply. Additionally we want to be able at some time to do for example mmapped
         PCI address space access on IA32 instead of port IO.
      
      - Rewrite the initialization code to don't use check_region at all. Add some
         comments there, which explain what's actually happening.
      
      - Fix creeping in of a c99 construct.
      
      - Make the main interrupt handler take a channel as data instead of the
         hwgroup. This is the entity an interrupt is physically associated with. PCI
         interrupt sharing is handled in a generically anyway. Analogously the main
         data entity of a device request queue (q->queuedata) is the device and not
         the hwgroup.  However right now we are only able to push it down to the
         channel level. The intention is to advance the choose_drive() function to
         just check for equal interrupt values for serialization of request and
         thus to get rid of the hwgroup altogether.

      [PATCH] 2.5.10 IDE 42 · 9dbf0015
      Martin Dalecki authored
      - Streamline the usage of sector_t over the strategy routines in question a
         bit. Streamline the do_request code in ide-disk.c.
      
      - Improve the readability of start_request in ide.c.
      
      - Remove obsolete/nowhere used stuff from hdreg.h.
      
      - Splitup special_t into classical flag field.
      
      - Use only a single field to determine the capacity of a drive.  Make this
         field and the code paths it follows as far as possible use the sector_t
         instead of a hard coded integer types.  This increases the chances that at
         some distant point in time we will indeed be able to use 64 bit wide sector_t
         entities. (Disks are getting huge those times now...)

      [PATCH] permit zero-length readahead, and tidy up readahead · 92216226
      Andrew Morton authored
      - Initialise the per-request_queue readahead parameter properly,
        rather than the dopey "if it's zero you get the deafult"
        approach.
      
      - Permit zero-length readahead.
      
      - 80-columnify mm/readahead.c
