staging: comedi: add bus-type-specific attach hooks for PCI and USB
The Comedi auto-configuration mechanism used to bind hardware devices to
comedi devices automatically is pretty kludgy. It fakes a "manual"
configuration of the comedi device as though the COMEDI_DEVCONFIG ioctl
(or the 'comedi_config' utility) were used. In particular, the
low-level comedi driver's '->attach()' routine is called with a pointer
to the struct comedi_device being attached and a pointer to a 'struct
devconfig' containing a device name string and a few integer options to
help the attach routine locate the device being attached. In the case
of PCI devices, these integer options are the PCI bus and slot numbers.
In the case of USB devices, there are no integer options and it relies
more on pot luck to attach the correct device.
This patch adds a couple of bus-type-specific attach routine hooks to
the struct comedi_driver, which a low-level driver can optionally fill
in if it supports auto-configuration.
A low-level driver that supports auto-configuration of {PCI,USB} devices
calls the existing comedi_{pci,usb}_auto_config() when it wishes to
auto-configure a freshly probed device (maybe after loading firmware).
This will call the new '->attach_{pci,usb}()' hook if the driver has
defined it, otherwise it will fall back to calling the '->attach()' hook
as before. The '->attach_{pci,usb}()' hook gets a pointer to the struct
comedi_device and a pointer to the struct {pci_dev,usb_interface} and
can figure out the {PCI,USB} device details for itself.

staging: comedi: don't hijack hardware device private data
comedi_auto_config() associates a Comedi minor device number with an
auto-configured hardware device and comedi_auto_unconfig() disassociates
it. Currently, these use the hardware device's private data pointer to
point to some allocated storage holding the minor device number. This
is a bit of a waste of the hardware device's private data pointer,
preventing it from being used for something more useful by the low-level
comedi device drivers. For example, it would make more sense if
comedi_usb_auto_config() was passed a pointer to the struct
usb_interface instead of the struct usb_device, but this cannot be done
currently because the low-level comedi drivers already use the private
data pointer in the struct usb_interface for something more useful.
This patch stops the comedi core hijacking the hardware device's private
data pointer. Instead, comedi_auto_config() stores a pointer to the
hardware device's struct device in the struct comedi_device_file_info
associated with the minor device number, and comedi_auto_unconfig()
calls new function comedi_find_board_minor() to recover the minor device
number associated with the hardware device.

cases, because calling that function in that context would free
memory that was in use. The aborted flag allows the lifetime to

Make the "word-at-a-time" helper functions more commonly usable
I have a new optimized x86 "strncpy_from_user()" that will use these
same helper functions for all the same reasons the name lookup code uses
them. This is preparation for that.
This moves them into an architecture-specific header file. It's
architecture-specific for two reasons:
- some of the functions are likely to want architecture-specific
implementations. Even if the current code happens to be "generic" in
the sense that it should work on any little-endian machine, it's
likely that the "multiply by a big constant and shift" implementation
is less than optimal for an architecture that has a guaranteed fast
bit count instruction, for example.
- I expect that if architectures like sparc want to start playing
around with this, we'll need to abstract out a few more details (in
particular the actual unaligned accesses). So we're likely to have
more architecture-specific stuff if non-x86 architectures start using
this.
(and if it turns out that non-x86 architectures don't start using
this, then having it in an architecture-specific header is still the
right thing to do, of course)
