      ide: add ide_host_add() helper · 6f904d01
      Bartlomiej Zolnierkiewicz authored
      Add ide_host_add() helper which does ide_host_alloc()+ide_host_register(),
      then convert ide_setup_pci_device[s](), ide_legacy_device_add() and some
      host drivers to use it.
      
      While at it:
      
      * Fix ide_setup_pci_device[s](), ide_arm.c, gayle.c, ide-4drives.c,
        macide.c, q40ide.c, cmd640.c and cs5520.c to return correct error value.
      
      * -ENOENT -> -ENOMEM in rapide.c, ide-h8300.c, ide-generic.c, au1xxx-ide.c
        and pmac.c
      
      * -ENODEV -> -ENOMEM in palm_bk3710.c, ide_platform.c and delkin_cb.c
      
      * -1 -> -ENOMEM in ide-pnp.c

      ide: pass hw_regs_t-s to ide_device_add[_all]() (take 3) · c97c6aca
      Bartlomiej Zolnierkiewicz authored
      * Add 'hw_regs_t **hws' argument to ide_device_add[_all]() and convert
        host drivers + ide_legacy_init_one() + ide_setup_pci_device[s]() to use

        [ However if host has > 1 port we must still set hwif->chipset to hint
          consecutive ide_find_port() call that the previous slot is occupied. ]
      
      * Unexport ide_init_port_hw().
      
      v2:
      * Use defines instead of hard-coded values in buddha.c, gayle.c and q40ide.c.
        (Suggested by Geert Uytterhoeven)
      
      * Better patch description.
      
      v3:
      * Fix build problem in ide-cs.c. (Noticed by Stephen Rothwell)

      IRQ: Maintain regs pointer globally rather than passing to IRQ handlers · 7d12e780
      David Howells authored
      Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
      of passing regs around manually through all ~1800 interrupt handlers in the
      Linux kernel.
      
      The regs pointer is used in few places, but it potentially costs both stack
      space and code to pass it around.  On the FRV arch, removing the regs parameter
      from all the genirq function results in a 20% speed up of the IRQ exit path
      (ie: from leaving timer_interrupt() to leaving do_IRQ()).
      
      Where appropriate, an arch may override the generic storage facility and do
      something different with the variable.  On FRV, for instance, the address is
      maintained in GR28 at all times inside the kernel as part of general exception
      handling.
      
      Having looked over the code, it appears that the parameter may be handed down
      through up to twenty or so layers of functions.  Consider a USB character
      device attached to a USB hub, attached to a USB controller that posts its
      interrupts through a cascaded auxiliary interrupt controller.  A character
      device driver may want to pass regs to the sysrq handler through the input
      layer which adds another few layers of parameter passing.
      
      I've build this code with allyesconfig for x86_64 and i386.  I've runtested the
      main part of the code on FRV and i386, though I can't test most of the drivers.
      I've also done partial conversion for powerpc and MIPS - these at least compile
      with minimal configurations.
      
      This will affect all archs.  Mostly the changes should be relatively easy.
      Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
      
      	struct pt_regs *old_regs = set_irq_regs(regs);
      
      And put the old one back at the end:
      
      	set_irq_regs(old_regs);
      
      Don't pass regs through to generic_handle_irq() or __do_IRQ().
      
      In timer_interrupt(), this sort of change will be necessary:
      
      	-	update_process_times(user_mode(regs));
      	-	profile_tick(CPU_PROFILING, regs);
      	+	update_process_times(user_mode(get_irq_regs()));
      	+	profile_tick(CPU_PROFILING);
      
      I'd like to move update_process_times()'s use of get_irq_regs() into itself,
      except that i386, alone of the archs, uses something other than user_mode().
      
      Some notes on the interrupt handling in the drivers:
      
       (*) input_dev() is now gone entirely.  The regs pointer is no longer stored in
           the input_dev struct.
      
       (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.  It does
           something different depending on whether it's been supplied with a regs
           pointer or not.
      
       (*) Various IRQ handler function pointers have been moved to type
           irq_handler_t.

      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.
