- pccbb no longer needs to remember whether a card is inserted.
- pccbb reissues insertion on load of cardbus/pccard modules.
- got rid of unnecessary delays in power functions.
- Cardbus children are no longer deleted if probe/attach fails.
- non-attached child devices are reprobed at driver_added.
* CARD interface to read CIS
- added card_cis_read/card_cis_free interface to read arbitrary CIS
data. This currently is only implemented in cardbus.
* pccard begins to work
- pccard can now use higher memory space (and uses it by default).
- set_memory_offset interface changed.
- fixed ccr access, which was broken at multiple locations.
- implement an interrupt handler - pccard can now share interrupts.
- resource alloc/release/activate/deactivate functions gutted: some
resources are allocated by the bridge before the child device is
probed or attached. Thus the resource "belongs" to the bridge, and
the pccard_*_resource functions need to fudge the owner/rid.
- changed some error conditions to panics to speed debugging.
* Mutex fix - Giant is entered at the beginning of thread
