40dd98a3bd Second half of the dev_t cleanup.
The big lines are:
	NODEV -> NULL
	NOUDEV -> NODEV
	udev_t -> dev_t
	udev2dev() -> findcdev()

Various minor adjustments including handling of userland access to kernel
space struct cdev etc.

ad925439e0 Device megapatch 4/6:
Introduce d_version field in struct cdevsw, this must always be
initialized to D_VERSION.

Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing
four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.

db5d831317 MFp4: Change struct fw_xfer to reduce memory copy in fwmem_*() functions.
And many changes.

* all
	- Major change of struct fw_xfer.
		o {send,recv}.buf is splitted into hdr and payload.

	- Remove unnecessary 'volatile' keyword.
	- Add definition of rtcode and extcode.

	- Change element of struct fw_bind for simplicity.
	- Check rtcode of response packet.
	- Reduce split transaction timeout to 200 msec.
		(100msec is the default value in the spec.)
	- Set watchdog timer cycle to 10 Hz.
	- Set xfer->tv just before calling fw_get_tlabel().

* fwohci.c
	- Simplifies fwohci_get_plen().

* sbp.c
	- Fix byte order of multibyte scsi_status informations.
	- Split sbp.c and sbp.h.
	- Unit number is not necessary for FIFO¤ address.
	- Reduce LOGIN_DELAY and SCAN_DELAY to 1 sec.
	- Add some constants defineded in SBP-2 spec.

* fwmem.c
	- Introduce fwmem_strategy() and reduce memory copy.

29b43e58e3 MFp4(simokawa_firewire):
Many internal structure changes for the FireWire driver.

- Compute CRC in CROM parsing.
- Add support for configuration ROM build.
- Simplify dummy buffer handling.
- busdma conversion
- Use swi_taskqueue_giant for -current.  Mark the interrupt routine as MPSAFE.
- AR buffer handling.
	Don't reallocate AR buffer but just recycle it.
	Don't malloc and copy per packet in fwohci_arcv().
	Pass packet to fw_rcv() using iovec.
	Application must prepare receiving buffer in advance.
- Change fw_bind API so that application should pre-allocate xfer structure.
- Add fw_xfer_unload() for recycling struct fw_xfer.
- Add post_busreset hook
- Remove unused 'sub' and 'act_type' in struct fw_xfer.
- Remove npacket from struct fw_bulkxfer.
- Don't call back handlers in fwochi_arcv() if the packet has
	not drained in AT queue
- Make firewire works on big endian platform.
- Use native endian for packet header and remove unnecessary ntohX/htonX.
- Remove FWXFERQ_PACKET mode.  We don't use it anymore.
- Remove unnecessary restriction of FWSTMAXCHUNK.
- Don't set root node for phy config packet if the root node is
	not cycle master capable but set myself for root node.
	We should be the root node after next bus reset.

Improve if_fwe performance.
- Simplify mbuf handling by using bulkxfer.
	Now, it uses mbuf clusters for RX buffer as usual ethernet drivers.
- Recycle struct xfer buffer and don't call malloc at runtime.
- Count input and output errors.
- Handle a mbuf chain longer than 6 correctly.
- Increase queue length.

0ae911eb0e Gigacommit to improve device-driver source compatibility between
branches:

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.

This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

15b70bcd2e MFp4(simokawa_sbp branch)
Improve SBP device probeing:
- Wait 2 sec before issuing LOGIN ORB expecting the reconnection
	hold timer expires.
- Serialize management ORB and scanning LUN by CAM on each target.
	This should fix the problem for devices which have multiple LUNs.
	Test device is donated by: Jaye Mathisen <mrcpu@internetcds.com>
- Freeze SIM queue for 2 sec after BUS RESET.
- Retry with LOGIN rather than RECONNECT after LOGIN is not completed for
	BUS RESET.
- Use appropriate CAM status for BUS RESET and DEVICE RESET.
- Let CAM to scan targets after BUS REST.
- Implement CAM scan target function.
- Keep our own devq freeze count.
- Let CAM to know that SBP does tagged queuing.

These should be merged to RELENG_4 before 4.8-RELEASE.

541937cf73 Cleanup of the d_mmap_t interface.
- Get rid of the useless atop() / pmap_phys_address() detour.  The
  device mmap handlers must now give back the physical address
  without atop()'ing it.
- Don't borrow the physical address of the mapping in the returned
  int.  Now we properly pass a vm_offset_t * and expect it to be
  filled by the mmap handler when the mapping was successful.  The
  mmap handler must now return 0 when successful, any other value
  is considered as an error.  Previously, returning -1 was the only
  way to fail.  This change thus accidentally fixes some devices
  which were bogusly returning errno constants which would have been
  considered as addresses by the device pager.
- Garbage collect the poorly named pmap_phys_address() now that it's
  no longer used.
- Convert all the d_mmap_t consumers to the new API.

I'm still not sure wheter we need a __FreeBSD_version bump for this,
since and we didn't guarantee API/ABI stability until 5.1-RELEASE.

- Fix overwrite problem of freed buffers. It was rare but could happen

- Drain AT queues and pend AR queues on SID receive rather than BUS reset to
