scw 2963ff5c58 Add `l_poll' to `struct linesw' and provide an xxxpoll() entry point 
in each tty driver to indirect through it.

This allows tty line-disciplines to handle poll(2) system calls.

thorpej 1c3a62e066 Sprinkle pmap_update() calls after calls to: 
- pmap_enter()
- pmap_remove()
- pmap_protect()
- pmap_kenter_pa()
- pmap_kremove()
as described in pmap(9).

These calls are relatively conservative.  It may be possible to
optimize these a little more.

mrg f1d2503dc5 rework pci_attach_hook() to just deal with the INO, not the full 
interrupt number.  properly find interrupts for the E250.  modify
pci_intr_map() accordingly.  retire psycho_intr_map().  deal with
INO values upto 0x3f, not upto 0x32.  restructure sabre_init() and
psycho_init() to be more similar, and display each psycho's IGN.
psycho_intr_establish() deals with INO upto 0x3f, values from 0x32
and higher get 0 for IPL.

tested on E250 & U5.

martin a7206004fc Faster error handling for iommu_dmamap_load_raw; avoid loading the map 
and unloading on error when we clearly can't get out without an error.

eeh 6c3bf28ffd Fix dvma problem caused by previous. Seems like the dvma segment calculation 
in iommu_dmamap_unload() was not quite right.

martin f4eec8f31f iommu_dvmamap_load_raw: add a check for creating maps larger than 
expected by the creator of the dma map and fail apropriately. This
makes the syssrc/dev/pci/if_vr.c driver work.

martin 97b57e69cc Make bus_dmamap_load_mbuf and bus_dmamap_load_uio use independend 
segment lists for their mapping; make iommu_dmamap_unload deal with
this type of maps.

Coded by Eduardo, tested (and minimaly tweaked) by me.

sommerfeld 851de295eb Change pci_intr_map to get interrupt source information from a "struct 
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".

This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.

Tested on alpha and i386; welcome to 1.5Q

nathanw 5127aa189d In fdioctl(), allocate fd_formb dynamically when needed, rather than on 
the stack, and remove the no-longer-necessary PHOLD()/PRELE() calls
in fdformat().

(This eliminates 1/3 of the instances of PHOLD()/PRELE() in the kernel code.)

XXX We still have too many mostly-redundant floppy drivers.
