d2b2128a28 Add stuff to support upcoming BMC/IPMI flashing of newer Dell machine
via the Linux tool.
     -  Add Linux shim to ipmi(4)
     -  Create a partitions file to linprocfs to make Linux fdisk see
        disks.  This file is dynamic so we can see disks come and go.
     -  Convert msdosfs to vfat in mtab since Linux uses that for
        msdosfs.
     -  In the Linux mount path convert vfat passed in to msdosfs
        so Linux mount works on FreeBSD.  Note that tasting works
        so that if da0 is a msdos file system
                /compat/linux/bin/mount /dev/da0 /mnt
        works.
     -  fix a 64it bug for l_off_t.
Grabing sh, mount, fdisk, df from Linux, creating a symlink of mtab to
/compat/linux/etc/mtab and then some careful unpacking of the Linux bmc
update tool and hacking makes it work on newer Dell boxes.  Note, probably
if you can't figure out how to do this, then you probably shouldn't be
doing it :-)

3619ea6a08 Don't right-adjust the SMBus slave address for SSIF IPMI BMCs enumerated
via ACPI either.  This is somewhat academic since we don't currently
support such devices though.

bb6bb7fe1b - Change ichsmb(4) to follow the format of all the other smbus controllers
for slave addressing by using left-adjusted slave addresses (i.e.
  xxxxxxx0b).
- Require the low bit of the slave address to always be zero in smb(4) to
  help catch broken applications.
- Adjust some code in the IPMI driver to not convert the slave address for
  SSIF to a right-adjusted address.  I (or possibly ambrisko@) added this in
  the past to (unknowingly) work around the bug in ichsmb(4).

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).

3745c395ec Rename the kthread_xxx (e.g. kthread_create()) calls
to kproc_xxx as they actually make whole processes.
Thos makes way for us to add REAL kthread_create() and friends
that actually make theads. it turns out that most of these
calls actually end up being moved back to the thread version
when it's added. but we need to make this cosmetic change first.

I'd LOVE to do this rename in 7.0  so that we can eventually MFC the
new kthread_xxx() calls.

72d7331539 Add support to the ipmi, isa attachment to attempt to read ipmi
config info. from device.hints.  Some machines have ipmi controllers
that do not have attachment info in either PCI, SMBIOS or ACPI.
This idea was hacked together by me and then done properly by
jhb.

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.

fab2d1adf6 The IPMI spec is ambiguous (or rather, it contradicts itself) about whether
or not the OS has to wait for RX_RDY or TX_RDY to be set before the OS sets
the control code in the control/status register.  Looking at the interface
design, it seems that RX_RDY and TX_RDY are probably there to protect
access to the data register and have nothing to do with the control/status
register.  Nevertheless, try to take what I think is the more conservative
approach and always wait for the appropriate [TR]X_RDY flag to be set
before writing any of the WR_NEXT, WR_END, RD_START, or RD_NEXT control
codes to the control/status register.

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.

Tom Rhodes, helped me with the man page.
