names suggest, they perform methods on Device's. In addition, they
check that the pointer passed to them is valid; if it isn't, they
pretend that the action failed. This fixes some crashes due to NULL
dereferences (e.g., PR 26509).

Frist, for pci slots, make the setup intr save the requested interrupt
vector and arg and return rather than passing it up to our parent. On
interrupts, we call this vector iff there's a card in the slot. This
should eliminate some of the hangs or "weird" messages that people see
when ejecting cards and also help close the race window somewhat.
Reading the pci bus one more time for this information is judged to be
an acceptible tradeoff since it is very very fast.
Cleanup a little how we detect unsupported cards. Only detect
unsupported cards (eg cardbus cards) on card insertion (or more
pedantically when a card is actually present). This should allow us
to change the message in the future to "cardbus card not supported
with OLDCARD" :-).
Note:
We may also consider this for the ISA bus case, but there the
reads are much more expensive and the location of the CD pin
status lines appears to be less standardized. Also, the ISA
management interrupt isn't shared with the card's interrupt.
The mutliplex the CSC and function interrupts bit also appears
to be non-standard (or at least not imlemented on all
bridges).
because NEWBUS (and I think some versions of Windows sometimes) writes
0xffffffff to these registers to disable them. When they are
"disabled" like this, writing memory ranges to the pcic registers are
ignored and you will get "card (null) (null)" when you insert a call
otherwise.
each of the bridge chips. Before we wrongly assumes that all cardbus
bridge chips were intel compatible step A/B. This mostly worked, but
likely caused problems with certain cirrus logic cardbus bridges.

- Mask GPCNTL against 0x1c (was 0xfc) for the reading of the NVRAM.
This ensures LEDC bit will not be set on 896 and later chips.

.cvsignore file for [A-Za-z]* to keep these directories around rather
than waste a file on .keepme. This should also make people's built
trees place nice with CVS.

allow call-specific authorization.
o Modify the authorization model so that p_can() is used to check
scheduling get/set events, using P_CAN_SEE for gets, and P_CAN_SCHED
for sets. This brings the checks in line with get/setpriority().

user runs with privilege, allowing the sending of icmp packets with
larger size (up to 48k, the default receive buffer size in ping),
which is useful for network driver development testing, as well
as experimentation with fragmentation.
