6fb77fef4d This is an MFC candidate.
ahc_eisa.c:
	Change aic7770_map_int to take an additional irq parameter.
	Although we can get the irq from the eisa dev under FreeBSD,
	we can't do this under linux, so the OSM interface must supply
	this.

ahc_pci.c:
	Move ahc_power_state_change() to the OSM.  This allows us to
	use a platform supplied function that does the same thing.
	-current will move to the FreeBSD native API in the near
	future.

aic7770.c:
	Sync up with core changes to support Linux EISA.

	We now store a 2 bit primary channel number rather
	than a bit flag that only allows b to be the primary
	channel.   Adjust for this change.

aic7xxx.c:
	Namespace and staticization cleanup.  All exported symbols
	use an "ahc_" prefix to avoid collisions with other modules.

	Correct a logic bug that prevented us from dropping
	ATN during some exceptional conditions during message
	processing.

	Take advantage of a new flag managed by the sequencer
	that indicates if an SCB fetch is in progress.  If so,
	the currently selected SCB needs to be returned to the
	free list to prevent an SCB leak.  This leak is a rarity
	and would only occur if a bus reset or timeout resulting
	in a bus reset occurred in the middle of an SCB fetch.

	Don't attempt to perform ULTRA transfers on ultra capable
	adapters missing the external precision resistor required
	for ultra speeds.  I've never encountered an adapter
	configured this way, but better safe than sorry.

        Handle the case of 5MHz user sync rate set as "0" instead of 0x1c
        in scratch ram.

        If we lookup a period of 0 in our table (async), clear the scsi offset.

aic7xxx.h:
	Adjust for the primary channel being represented as
	a 2 bit integer in the flags member of the ahc softc.

	Cleanup the flags definitions so that comment blocks are
	not cramped.

	Update seeprom definitions to correctly reflect the fact
	that the primary channel is represented as a 2 bit integer.

	Add AHC_ULTRA_DIASABLED softc flag to denote controllers
	missing the external precision resistor.

aic7xxx.reg:
	Add DFCACHETH to the definition of DFSTATUS for completness sake.

	Add SEQ_FLAGS2 which currently only contains the SCB_DMA
	(SCB DMA in progress) flag.

aic7xxx.seq:
	Correct a problem when one lun has a disconnected untagged
	transaction and another lun has disconnected tagged transactions.
	Just because an entry is found in the untagged table doesn't
	mean that it will match.  If the match on the lun fails, cleanup
	the SCB (return it to the disconnected list or free it), and snoop
	for a tag message.  Before this change, we reported an unsolicited
	reselection.  This bug was introduced about a month ago during an
	overly aggressive optimization pass on the reselection code.

	When cleaning up an SCB, we can't just blindly free the SCB.  In
	the paging case, if the SCB came off of the disconnected list, its
	state may never have been updated in host memory.  So, check the
	disconnected bit in SCB_CONTROL and return the SCB to the disconnected
	list if appropriate.

	Manage the SCB_DMA flag of SEQ_FLAGS2.

	More carefully shutdown the S/G dma engine in all cases by using
	a subroutine.  Supposedly not doing this can cause an arbiter hang
	on some ULTRA2 chips.

	Formatting cleanup.

	On some chips, at least the aic7856, the transition from
	MREQPEND to HDONE can take a full 4 clock cycles.  Test
	HDONE one more time to avoid this race.  We only want our
	FIFO hung recovery code to execute when the engine is
	really hung.

aic7xxx_93cx6.c:
	Sync perforce ids.

aic7xxx_freebsd.c:
	Adjust for the primary channel being a 2 bit integer
	rather than a flag for 'B' channel being the primary.

	Namespace cleanup.

	Unpause the sequencer in one error recovery path that
	neglected to do so.  This could have caused us to perform
	a bus reset when a recovery message might have otherwise been
	successful.

aic7xxx_freebsd.h:
	Use AHC_PCI_CONFIG for controlling compilation of PCI
	support consistently throughout the driver.

	Move ahc_power_state_change() to OSM.

aic7xxx_inline.h
	Namespace cleanup.

	Adjust our interrupt handler so it will work in the edge
	interrupt case.  We must process all interrupt sources
	when the interrupt fires or risk not ever getting an
	interrupt again.  This involves marking the fact
	that we are relying on an edge interrupt in ahc->flags
	and checking for this condition in addition to the
	AHC_ALL_INTERRUPTS flag.  This fixes hangs on the
	284X and any other aic7770 installation where level
	interrupts are not available.

aic7xxx_pci.c:
	Move the powerstate manipulation code into the OSM.  Several
	OSes now provide this functionality natively.

	Take another shot at using the data stored in scratch ram
	if the SCB2 signature is correct and no SEEPROM data is
	available.  In the past this failed if external SCB ram
	was configured because the memory port was locked.  We
	now release the memory port prior to testing the values
	in SCB2 and re-acquire it prior to doing termination control.

	Adjust for new 2 bit primary channel setting.

	Trust the STPWLEVEL setting on v 3.X BIOSes too.

	Configure any 785X ID in the same fashion and assume
	that any device with a rev id of 1 or higher has the
	PCI 2.1 retry bug.

136446540a When aio_read/write() is used on a raw device, physical buffers are
used for up to "vfs.aio.max_buf_aio" of the requests.  If a request
size is MAXPHYS, but the request base isn't page aligned, vmapbuf()
will map the end of the user space buffer into the start of the kva
allocated for the next physical buffer.  Don't use a physical buffer
in this case.  (This change addresses problem report 25617.)

When an aio_read/write() on a raw device has completed, timeout() is
used to schedule a signal to the process.  Thus, the reporting is
delayed up to 10 ms (assuming hz is 100).  The process might have
terminated in the meantime, causing a trap 12 when attempting to
deliver the signal.  Thus, the timeout must be cancelled when removing
the job.

aio jobs in state JOBST_JOBQGLOBAL should be removed from the
kaio_jobqueue list during process rundown.

During process rundown, some aio jobs might move from one list to a
different list that has already been "emptied", causing the rundown to
be incomplete.  Retry the rundown.

A call to BUF_KERNPROC() is needed after obtaining a physical buffer
to disassociate the lock from the running process since it can return
to userland without releasing that lock.

5951069a87 netgraph.h:
Change a prototype.
  Add a function version of ng_ref_node() when debugging so
  a breakpoint can be set on it.
ng_base.c:
  add 'node' as an argument to ng_apply_item so that it is up
  to the caller to take over and release the item's reference on
  the node. If the release reports back that the node went away
  due to the reference going to 0, the caller should cease referencing
  the now defunct node. (e.g. the item was a 'kill node' message).
  Alter ng_unref_node to report back the residual references as a result.
ng_pptpgre.c:
  Don't reference a node after we dropped a reference to it.
  (What if it was the last?)
Fixes a node leak reported by Harti Brandt <brandt@fokus.gmd.de>
 which was due to an incorrect earlier attempt to fix the
 "accessing node after dropping the last reference" problem.

Mark Murray
02c986ab54 Very large makeover of the /dev/random driver.
o Separate the kernel stuff from the Yarrow algorithm. Yarrow is now
  well contained in one source file and one header.

o Replace the Blowfish-based crypto routines with Rijndael-based ones.
  (Rijndael is the new AES algorithm). The huge improvement in
  Rijndael's key-agility over Blowfish means that this is an
  extremely dramatic improvement in speed, and makes a heck of
  a difference in its (lack of) CPU load.

o Clean up the sysctl's. At BDE's prompting, I have gone back to
  static sysctls.

o Bug fixes. The streamlining of the crypto stuff enabled me to
  find and fix some bugs. DES also found a bug in the reseed routine
  which is fixed.

o Change the way reseeds clear "used" entropy. Previously, only the
  source(s) that caused a reseed were cleared. Now all sources in the
  relevant pool(s) are cleared.

o Code tidy-up. Mostly to make it (nearly) 80-column compliant.
