Solve the continuous stream of spurious IRQ 7's that occur on machines
with AMDX2 (dual core) cpus. It's a BIOS bug. If a BIOS running this cpu
does not set the LINTEN bit in the Hyper Transport Transaction Control
Register, incoming interrupts from the 8259 will go the INTR/NMI pins for
BOTH cpus, causing *TWO* interrupt ack cycles (one from each cpu). The
second cycle usually results in a spurious interrupt vector (typically IRQ 7)
getting hit. The spurious interrupt vector is not subject to the 8259's
interrupt masks.
At the moment the fix requires specifying a cpu option in your kernel config:
options CPU_AMD64X2_INTR_SPAM
This problem can occur when the kernel is operating in ICU (8259) mode,
in an SMP configuration, or if you are attempting to route
one or more ISA interrupts, such as the 8254 clock, through the 8259 in
an SMP configuration.
When the bit is set, the incoming INTR/NMI is routed to both LAPIC's
LINT0/LINT1, which is what we expect. When the bit is not set, INTR/NMI
goes to both cpus simultaniously, which is bad. In addition, having both
the LAPIC and the 8259 responding to the INTA bus cycle can create serious
general interrupt routing issues.
Symptoms of the problem:
* The 8259 never gets routed through to LINT0/LINT1, no matter how the
IMCR is set or what the MPTable reports.
* Every 8259 interrupt causes an additional spurious interrupt to occur.
* Interrupt routing in general is more severely broken then usual.
* The kernel is unable to get the 8254 clock interrupt routed.
PS: This took 30 man hours to locate, so give me credit if you transplant
it please!

Use the new BUS_ADD_CHILD and IVARS recursion capability to still allow
the pcib's under legacypci to get nexus generated IVARS.
NOTE ON IVARS: These can be utterly confusing because a BUS device may
manage and control the IVARS attached to its children. In addition, if the
BUS method for the device accessing the IVARs does not properly match up
with or recurse to the device that actually created the ivars, mass
confusion can result. I have attempted to document the issue but XXX it
needs some sanity check code.

possible PCI mainbus subsystems actually own the PCI mainbus. This is not
yet tied into ACPI but will be soon. No longer add legacy "pcib" busses
if it is detected that another subsystem controls the mainbus. Before
the busses were added but then simply not scanned later on, creating
confusing pcibX designations. Now the busses aren't added... legacypci
stops cold if it doesn't own the PCI mainbus. Get rid of the twisted
checks for "pci" devices that used to handle this job.
Document many aspects of the PCI code and redo some of the APIs slightly
to make them more obvious. In particular, document the odd fact that
pci_*() accessor function actually operate on a pci function code based
sub-device of the "pci" driver and call device_get_parent() to get to the
pci" driver layer. This sub layer really needs its own formal designation.
Change "pciX" attachments to "pcibY" busses. Use the secondary bus id
for 'X' and require it to be unique. Also reorder "pcibY" attachments
so the physical bus number tends to (but is not guarenteed to be) the
same 'Y' in pcibY.

"pcib" device be passed to pcib_get/set_*() routines instead of children

Cleanup some of the newbus infrastructure.
* Change the device_identify API to return success/failure, like
most of the other newbus methods. This may be used for conflict
resolution in the future.
* Clearly document the device_identify method and formalize its use
by adding discrimination between initial bus probes and bus rescans.
Do not re-execute static identification code that has already been run
every time a new driver is added at run-time.
* Clearly document the do-ISA-last hack.
* Provide generic routines for the most common device_identify operations
(psueo or synthesized devices that operate under other devices, such as
lpt operating under ppbus, which are not 'scanned' by the parent bus).
* Remove the hacks that install and initialize the nexus device. Instead,
use the existing DRIVER_MODULE infrastructure to install nexus under
root_bus.
* Document the boot-time initialization path so it doesn't take the next
guy 8 hours to figure out what code is actually being run when.

Fix a long-standing bug in the livelock code. An interrupt thread normally
unmasks the hardware interrupt source when it is through. However, if a
livelock occurs the interrupt thread may be polled long after a device has
terminated operations and torn down its interrupt. To solve this problem,
only unmask the hardware interrupt if the IRQ still has device handlers
installed. This fixes a weird problem with the parallel port driver
(which installs and tears-down IRQ 7 on each write() for some unfathomable
reason).

Redo the interrupt livelock code. Simplify the frequency calculations
and add a 1-second stabilization requirement before a livelock is removed.
Fix a bug that prevented the code from actually limiting the interrupt rate
properly.
Greatly simplify ithread_done() and rename it to ithread_unmask(). It is
no longer responsible for putting the interrupt thread to sleep.
There is one issue left and that is the livelock code must re-enable the
interrupt at the limit frequency in order to detect when the actual
interrupt rate falls below the low water mark. In a livelocked situation
the actual interrupt rate will be about 2x the livelock limit because
both the systimer interrupt and the livelocked interrupt will be running.

Temporary hack until corecode can fix it. There is a p_rtprio and also
a lwp_rtprio. The scheduler was using lwp_rtprio but proc0 only initialized
p_rtprio, so all processes wound up with RTP_PRIO_REALTIME instead of
RTP_PRIO_NORMAL. This basically turned off the estcpu priority code and
made all runnable processes round robin equally.

Remove the dummy IPI messaging routines for UP builds and properly
conditionalize the use of IPI messages in various core kernel modules.
Change the callback from func(arg, frameptr) to func(arg1, arg2, frameptr),
where the new argument (arg2) is an integer supplied by the originator.
Create wrappers for simpler versions of the callback: func(arg1), and
func(arg1, arg2) (for the moment we presume that GCC will generate code
for the full-sized three-argument callback which is compatible with one
and two-argument function pointers).
This extension to the IPI messaging code is needed to properly implement
MP-safe tsleep/wakeup code. Although the extra argument is superfluous in
most cases, the overhead of doing an IPI is such that there should be no
noticeable impact on performance.
