      pcmcia: use autoconfiguration feature for ioports and iomem · 00990e7c
      Dominik Brodowski authored
      When CONF_AUTO_SET_IO or CONF_AUTO_SET_IOMEM are set, the corresponding
      fields in struct pcmcia_device *p_dev->resource[0,1,2] are set
      accordinly. Drivers wishing to override certain settings may do so in
      the callback function, but they no longer need to parse the CIS entries
      stored in cistpl_cftable_entry_t themselves.

      pcmcia: introduce autoconfiguration feature · 440eed43
      Dominik Brodowski authored
      Introduce an autoconfiguration feature to set certain values in
      pcmcia_loop_config(), instead of copying the same code over and over
      in each PCMCIA driver. At first, introduce the following options:
      
      CONF_AUTO_CHECK_VCC	check or matching Vcc entry
      CONF_AUTO_SET_VPP	set Vpp
      CONF_AUTO_AUDIO		enable the speaker line

      pcmcia: convert pcmcia_request_configuration to pcmcia_enable_device · 1ac71e5a
      Dominik Brodowski authored
      pcmcia_enable_device() now replaces pcmcia_request_configuration().
      Instead of config_req_t, all necessary flags are either passed as
      a parameter to pcmcia_enable_device(), or (in rare circumstances)
      set in struct pcmcia_device -> flags.
      
      With the last remaining user of include/pcmcia/cs.h gone, remove
      all references.

      pcmcia: simplify IntType · 37979e15
      Dominik Brodowski authored
      IntType was only set to INT_MEMORY (driver pcmciamtd) or INT_MEMORY_AND_IO
      (all other drivers). As this flags seems to relate to ioport access, make
      it conditional to the driver having requested IO port access. There are two
      drivers which do not request IO ports, but did set INT_MEMORY_AND_IO:
      ray_cs and b43. For those, we consistently only set INT_MEMORY in future.

      pcmcia: do not use io_req_t when calling pcmcia_request_io() · 90abdc3b
      Dominik Brodowski authored
      Instead of io_req_t, drivers are now requested to fill out
      struct pcmcia_device *p_dev->resource[0,1] for up to two ioport
      ranges. After a call to pcmcia_request_io(), the ports found there
      are reserved, after calling pcmcia_request_configuration(), they may
      be used.

      pcmcia: dev_node removal (write-only drivers) · 317b6d63
      Dominik Brodowski authored
      dev_node_t was only used to transport some minor/major numbers
      from the PCMCIA device drivers to deprecated userspace helpers.
      However, only a few drivers made use of it, and the userspace
      helpers are deprecated anyways. Therefore, get rid of dev_node_t .
      
      As a first step, remove any usage of dev_node_t from drivers which
      only wrote to this typedef/struct, but did not make use of it.

      pcmcia: re-work pcmcia_request_irq() · eb14120f
      Dominik Brodowski authored
      Instead of the old pcmcia_request_irq() interface, drivers may now
      choose between:
      
      - calling request_irq/free_irq directly. Use the IRQ from *p_dev->irq.
      
      - use pcmcia_request_irq(p_dev, handler_t); the PCMCIA core will
        clean up automatically on calls to pcmcia_disable_device() or
        device ejection.
      
      - drivers still not capable of IRQF_SHARED (or not telling us so) may
        use the deprecated pcmcia_request_exclusive_irq() for the time
        being; they might receive a shared IRQ nonetheless.

      pcmcia: rework the irq_req_t typedef · 5fa9167a
      Dominik Brodowski authored
      Most of the irq_req_t typedef'd struct can be re-worked quite
      easily:
      
      (1) IRQInfo2 was unused in any case, so drop it.
      
      (2) IRQInfo1 was used write-only, so drop it.
      
      (3) Instance (private data to be passed to the IRQ handler):
      	Most PCMCIA drivers using pcmcia_request_irq() to actually
      	register an IRQ handler set the "dev_id" to the same pointer
      	as the "priv" pointer in struct pcmcia_device. Modify the two
      	exceptions (ipwireless, ibmtr_cs) to also work this waym and
      	set the IRQ handler's "dev_id" to p_dev->priv unconditionally.
      
      (4) Handler is to be of type irq_handler_t.
      
      (5) Handler != NULL already tells whether an IRQ handler is present.
      	Therefore, we do not need the IRQ_HANDLER_PRESENT flag in
      	irq_req_t.Attributes.

      [PATCH] remove many unneeded #includes of sched.h · cd354f1a
      Tim Schmielau authored
      After Al Viro (finally) succeeded in removing the sched.h #include in module.h
      recently, it makes sense again to remove other superfluous sched.h includes.
      There are quite a lot of files which include it but don't actually need
      anything defined in there.  Presumably these includes were once needed for
      macros that used to live in sched.h, but moved to other header files in the
      course of cleaning it up.
      
      To ease the pain, this time I did not fiddle with any header files and only
      removed #includes from .c-files, which tend to cause less trouble.
      
      Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
      arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
      allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
      configs in arch/arm/configs on arm.  I also checked that no new warnings were
      introduced by the patch (actually, some warnings are removed that were emitted
      by unnecessarily included header files).

      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.
