1710852ebd Don't try to stop the IPMI watchdog timer if it is not running.
Starting or stopping the IPMI watchdog is rather expensive with the
current implementation as all IPMI requests are bounced via thread.
This is not viable during shutdown or dumps, and this avoids headache
in the common case that the watchdog is not enabled.  The IPMI watchdog
should probably be reworked to not use a separate thread to fix this
in the case when the watchdog timer is enabled.

6472ac3d8a Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs.
The SYSCTL_NODE macro defines a list that stores all child-elements of
that node. If there's no SYSCTL_DECL macro anywhere else, there's no
reason why it shouldn't be static.

d745c852be Mark MALLOC_DEFINEs static that have no corresponding MALLOC_DECLAREs.
This means that their use is restricted to a single C file.

a46a1e767d - Fixed incorrect watchdog timeout setting: MSB of a 2-byte
value is obtained by dividing it by 256, not by 2550; also,
  one second is 10^9 nanoseconds, not 1800000000 nanoseconds.

- Due to rounding error, setting watchdog to a really small
  timeout (<1 sec) was turning the watchdog off.  It should
  set the watchdog to a small timeout instead.

- Implemented error checking in ipmi_wd_event(), as required
  by watchdog(9).

PR:		kern/130512
Submitted by:	Dmitrij Tejblum

- Additionally, check that the timeout value is within the
  supported range, and if it's too large, act as required by
  watchdog(9).

943bebd2c9 Remove hack attempt at using devfs cloning for per-file descriptor storage.
Use the much simpler cdevpriv for per-fd state and enable it.  This allows
multiple opens of /dev/ipmi0 (e.g. using ipmitool while ipmievd is running
in the background).

f29fa1dfa4 Revisit the watchdogs: Resetting the error to EINVAL after failing to set the
watchdog might hide the succesful arming of an earlier one. Accept that on
failing to arm any watchdog (because of non-supported timeouts) EOPNOTSUPP is
returned instead of the more appropriate EINVAL.

9079fff550 Align the interfaces for the various watchdogs and make the interface
behave as expected.

Also:
- Return an error if WD_PASSIVE is passed in to the ioctl as only
  WD_ACTIVE is implemented at the moment. See sys/watchdog.h for an
  explanation of the difference between WD_ACTIVE and WD_PASSIVE.
- Remove the I_HAVE_TOTALLY_LOST_MY_SENSE_OF_HUMOR define. If you've
  lost your sense of humor, than don't add a define.

Specific changes:

i80321_wdog.c
  Don't roll your own passive watchdog tickle as this would defeat the
  purpose of an active (userland) watchdog tickle.

ichwd.c / ipmi.c:
  WD_ACTIVE means active patting of the watchdog by a userland process,
  not whether the watchdog is active. See sys/watchdog.h.

kern_clock.c:
  (software watchdog) Remove a check for WD_ACTIVE as this does not make
  sense here. This reverts r1.181.

d72a078647 Update the ipmi(4) driver:
- Split out the communication protocols into their own files and use
  a couple of function pointers in the softc that the commuication
  protocols setup in their own attach routine.
- Add support for the SSIF interface (talking to IPMI over SMBus).
- Add an ACPI attachment.
- Add a PCI attachment that attaches to devices with the IPMI interface
  subclass.
- Split the ISA attachment out into its own file: ipmi_isa.c.
- Change the code to probe the SMBIOS table for an IPMI entry to just use
  pmap_mapbios() to map the table in rather than trying to setup a fake
  resource on an isa device and then activating the resource to map in the
  table.
- Make bus attachments leaner by adding attach functions for each
  communication interface (ipmi_kcs_attach(), ipmi_smic_attach(), etc.)
  that setup per-interface data.
- Formalize the model used by the driver to handle requests by adding an
  explicit struct ipmi_request object that holds the state of a given
  request and reply for the entire lifetime of the request.  By bundling
  the request into an object, it is easier to add retry logic to the various
  communication backends (as well as eventually support BT mode which uses
  a slightly different message format than KCS, SMIC, and SSIF).
- Add a per-softc lock and remove D_NEEDGIANT as the driver is now MPSAFE.
- Add 32-bit compatibility ioctl shims so you can use a 32-bit ipmitool
  on FreeBSD/amd64.
- Add ipmi(4) to i386 and amd64 NOTES.

37b1ce132c Add an OpenIPMI mostly compatible driver. This driver was developed
to work with ipmitools.  It works with other tools that have an OpenIPMI
driver interface.  The port will need to get updated to used this.
I have not implemented the IPMB mode yet so ioctl's for that don't
really do much otherwise it should work like the OpenIPMI version.
The ipmi.h definitions was derived from the ipmitool header file.
The bus attachments are done for smbios and pci/smbios.  Differences
in bus probe order for modules/static are delt with.  ACPI attachment
should be done.

This drivers registers with the watchdod(4) interface

Work to do:
     - BT interface
     - IPMB mode

This has been tested on Dell PE2850, PE2650 & PE850 with i386 & amd64
kernel.

I will link this into the build on next week.
