- Do a bunch of gratuitous changes intended to make the code easier to follow. * Rename/reorder all of the pccard structures, change many of the member names to be descriptive, and follow more closely other 'bus' drivers naming schemes. * Rename a bunch of parameter and local variable names to be more consistant in the code. * Renamed the PCCARD 'crd' device to be the 'card' device * KNF and make the code consistant where it was obvious. * ifdef'd out some unused code 1997-10-26 04:36:24 +00:00			`struct pccard_device;`

Update the PCIC controller's imask with individual slot IRQ's. Assuming that the intr_mask[] was updated by changing the maskptrs (the existing update_intr_masks() function will not work) this code was written so the PCIC controller insertion/removal events will not interrupt the card IRQ handler events. Some possible scenarios: + Card is removed during IRQ handler: - PCIC card handler is allowed to interrupt - card removal event is called, removing the driver and data structures * card interrupt handler continues w/out driver, data structures, and hardware OR (the code just committed) * card IRQ handler has no hardware to read/write to, but has code and data to run on (XXX- Assume it completes and doesn't spin forever) - PCIC card handler unloads the card driver The current situation at least leaves the card interrupt handlers the drivers and data structures to work with although the hardware can't be guaranteed.

- 'Beep' support now happens in it's own separate file, so you can mess around with different noises for the different events and not have it affect other files. Inspired by: PAO 1997-10-26 06:06:54 +00:00			`enum beepstate { BEEP_ON, BEEP_OFF };`
