63b0786f0c Add ACPI lock support.
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.

03b5e1982a Add ACPI subsystem mutex support, currently disabled. This implements
a private mutex we can use to wrap the ACPI subsystem proper.

a9cf0dff08 Use msleep() when we sleep waiting for a GPE, since we are holding the
ACPI mutex.

Add some comments to EcWaitEventIntr.

Clean up deviant style, add debugging to be consistent.

cb9b0d80fb Update to synch with the 20010615 ACPI CA import.
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.

f664aeee49 Use the new-born BIO_CMD1 instead of fudging a bio_flag value for reading
the sector ID.

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. ;-)

323fed60a5 Two more "oops"es here: i didn't mean to turn on fdc debugging by
default in the KLD, and to turn off pccard support, so reverse each of
the flags.  Also, the flags should be overridable by /etc/make.conf.

5937458054 Define BIO_CMD{1,2}, available for local hacks, similar to the already
existing BIO_FLAG{1,2}.  To be used in the fdc(4) driver soon.

8bf82a92d5 Backout CSRG revision 7.22 to this file (if in_losing notices an
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.

5f431174f3 This change slipped through hidden in a CVS conflict. Logically belongs

e219897a2a First stab at fixing resource deallocation, and implementing fdc(4) as
a KLD.  Still doesn't work well except in the PCMCIA case (now if only
pccardd(8) could load and unload drivers dynamically...).  Mainly, it
tries to find fdc0 on the PCI bus for whatever obscure reasons, but i
need someone who understands driver(9) to fix this.  However, it's at least
already better than before, and i'm tired of maintaining too many private
changes in my tree, given the large patches bde submitted. :)

64860614a4 Merge in parts of a larger patchset i received from Bruce. Untested
by now (except of a compile test), but i believe this to contain no
actual functional changes.

. Fix the copyright of the Regents i accidentally broke in rev 1.197
  (although only a very small part of the original driver survived
  at all...).

. Bump MAX_CYLINDER since some obscure formats really use more than 80
  cylinders.

. Correctly handle BIO_FORMAT which used to be a bitmask but is now a BIO
  command of its own.

. Numerous stylistic fixes.

c5ba0be495 Sync to my work in progress:
- Reorder the acpi_* functions in a sensible fashion
 - Add acpi_ForeachPackageObject and acpi_GetHandleInScope
 - Use the new debugging layer/level names
 - Implement most of the guts of the acpi_thermal module; passive cooling
   isn't there yet, but active cooling should work.
 - Implement power resource handling (acpi_powerres.c)

This compiles and mostly works, but my test coverage is small, so feedback
is welcome.
