b2073c7d9e First pass at softc list locking for if_ppp.c. Many parts of
this patch were submitted by Maurycy Pawlowski-Wieronski.  In addition
to Maurycy's change, break out softc tear down from ppp_clone_destroy()
into ppp_destroy() rather than performing a convoluted series of
extraction casts and indirections during tear down at mod unload.

8a148d55b7 Moved the function pointer in struct puc_device_description to the end
of the struct, so that a placeholder for it (or unportable C99
initializers) are not needed for entries that don't use it.  Use a C99
initializer for the 1 entry that uses it.  Removed 91 placeholders.
This also restores API compatibility with NetBSD and RELENG_4 for most
entries.

d4e132ea17 Fixed some style bugs (tab lossage) in rev.1.26.
Removed the requirement for a particular subvendor/subproduct in
rev.1.26 (VScom PCI-800L card).  While the BARs, etc., may depend on
the sub-ids, this is not known to be so, and I think it is better to
guess that they don't.  The decision to check sub-id checks in this
file is apparently random; for VScom cards they were checked in 3 of
8 cases.

212b6d5244 + rename and document an unused field in struct arpcom (field is still
there so there are no ABI changes);
+ replace 5 redefinitions of the IPF2AC macro with one in if_arp.h

Eventually (but before freezing the ABI) we need to get rid of
struct arpcom (initially with the help of some smart #defines
to avoid having to touch each and every driver, see below).

Apart from the struct ifnet, struct arpcom now only stores a copy
of the MAC address (ac_enaddr, but we already have another copy in
the struct ifnet -- if_addrhead), and a netgraph-specific field
which is _always_ accessed through the ifp, so it might well go
into the struct ifnet too (where, besides, there is already an entry
for AF_NETGRAPH data...)

Too bad ac_enaddr is widely referenced by all drivers. But
this can be fixed as follows:

#define ac_enaddr       ac_if.the_original_ac_enaddr_in_struct_ifnet

(note that the right hand side would likely be a pointer rather than
the base address of an array.)

c61314601b Add support for the HP Modular Smart Array 20 & 500 storage arrays.
Logical volumes on these devices show up as LUNs behind another
controller (also known as proxy controller).  In order to issue
firmware commands for a volume on a proxy controller, they must be
targeted at the address of the proxy controller it is attached to,
not the Host/PCI controller.

A proxy controller is defined as a device listed in the INQUIRY
PHYSICAL LUNS command who's L2 and L3 SCSI addresses are zero.  The
corresponding address returned defines which "bus" the controller
lives on and we use this to create a virtual CAM bus.

A logical volume's addresses first byte defines the logical drive
number.  The second byte defines the bus that it is attached to
which corresponds to the BUS of the proxy controller's found or the
Host/PCI controller.

Change event notification to be handled in its own kernel thread.
This is needed since some events may require the driver to sleep
on some operations and this cannot be done during interrupt context.
With this change, it is now possible to create and destroy logical
volumes from FreeBSD, but it requires a native application to
construct the proper firmware commands which is not publicly
available.

Special thanks to John Cagle @ HP for providing remote access to
all the hardware and beating on the storage engineers at HP to
answer my questions.

7870c3c61c - Enable (unmask) interrupt sources earlier in the ithread loop.
Specifically, we used to enable the source after locking sched_lock
  and just before we had already decided to do a context switch.
  This meant that an ithread could never process more than one interrupt
  per context switch.  Enabling earlier in the loop before sched_lock is
  acquired allows an ithread to handle multiple interrupts per context
  switch if interrupts fire very rapidly.  For the case of heavy interrupt
  load this can reduce the number of context switches (and thus overhead)
  as well as reduce interrupt latency.
- Now that we can handle multiple interrupts per context switch, add simple
  interrupt storm protection to threaded interrupts.  If X number of
  consecutive interrupts are triggered before the itherad voluntarily
  yields to another thread, then the interrupt thread will sleep with the
  associated interrupt source disabled (masked) for 1/10th of a second.
  The default value of X is 500, but it can be tweaked via the tunable/
  sysctl hw.intr_storm_threshold.  If an interrupt storm is detected, then
  a message is output to the kernel console on the first occurrence per
  interrupt thread.  Interrupt storm protection can be disabled completely
  by setting this value to 0.  There is no scientific reasoning for the
  1/10th of a second or 500 interrupts values, so they may require tweaking
  at some point in the future.

Tested by:	rwatson (an earlier version w/o the storm protection)
Tested by:	mux (reportedly made a machine with two PCI interrupts
		storming usable rather than hard locked)
