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().

Pass the softc, not the device_t to the Notify handler.
Don't invoke the Interpreter from callout context, as it may sleep.
Use AcpiOsQueueForExecution, which is called from taskqueue_swi.
Add an ACPI subsystem mutex, and macros for handling it. Because it's
not possible to differentiate between ACPI CA acquiring mutexes for
internal use and for use by AML, and because AML in the field doesn't
handle mutexes correctly, we can't use the ACPI subsystem's internal
locking. In addition, we have other private data of our own to lock.
Add initial locking to the ACPI driver code and the thermal module.
These locks are currently inoperative.
Pull some errant style back into line.

Based on numerous comments made by Bruce, rewrite a good part of the
old fdformat() function, and merge it with fdreadid() into a single
unified fdmisccmd() function. Various style and a couple of more
serious bugs fixed there.
While i was at it, i also fixed the long-standing "TODO: don't
allocate buffer on stack." in fdcioctl(), fixed a number of style bugs
there, and finally implemented the FD_DEBUG ioctl command that has
been advertised in <sys/fdcio.h> (formerly <machine/ioctl_fd.h>) for
almost seven years now. ;-)

RTF_DYNAMIC route, it got freed twice). I am not sure what was
the actual problem in 1992, but the current behavior is memory
leak if PCB holds a reference to a dynamically created/modified
routing table entry. (rt_refcnt>0 and we don't call rtfree().)
My test bed was:
1. Set net.inet.tcp.msl to a low value (for test purposes), e.g.,
5 seconds, to speed up the transition of TCP connection to a
"closed" state.
2. Add a network route which causes ICMP redirect from the gateway.
3. ping(8) host H that matches this route; this creates RTF_DYNAMIC
RTF_HOST route to H. (I was forced to use ICMP to cause gateway
to generate ICMP host redirect, because gateway in question is a
4.2-STABLE system vulnerable to a problem that was fixed later in
ip_icmp.c,v 1.39.2.6, and TCP packets with DF bit set were
triggering this bug.)
4. telnet(1) to H
5. Block access to H with ipfw(8)
6. Send something in telnet(1) session; this causes EPERM, followed
by an in_losing() call in a few seconds.
7. Delete ipfw(8) rule blocking access to H, and wait for TCP
connection moving to a CLOSED state; PCB is freed.
8. Delete host route to H.
9. Watch with netstat(1) that `rttrash' increased.
10. Repeat steps 3-9, and watch `rttrash' increases.
