- Implement an ICH-comptabile PCI interrupt router on the lpc device with
8 steerable pins configured via config space access to byte-wide
registers at 0x60-63 and 0x68-6b.
- For each configured PCI INTx interrupt, route it to both an I/O APIC
pin and a PCI interrupt router pin. When a PCI INTx interrupt is
asserted, ensure that both pins are asserted.
- Provide an initial routing of PCI interrupt router (PIRQ) pins to
8259A pins (ISA IRQs) and initialize the interrupt line config register
for the corresponding PCI function with the ISA IRQ as this matches
existing hardware.
- Add a global _PIC method for OSPM to select the desired interrupt routing
configuration.
- Update the _PRT methods for PCI bridges to provide both APIC and legacy
PRT tables and return the appropriate table based on the configured
routing configuration. Note that if the lpc device is not configured, no
routing information is provided.
- When the lpc device is enabled, provide ACPI PCI link devices corresponding
to each PIRQ pin.
- Add a VMM ioctl to adjust the trigger mode (edge vs level) for 8259A
pins via the ELCR.
- Mark the power management SCI as level triggered.
- Don't hardcode the number of elements in Packages in the source for
the DSDT. iasl(8) will fill in the actual number of elements, and
this makes it simpler to generate a Package with a variable number of
elements.

It starts off being used to track the grammar for the number of disks

Replace the variable with disks_grammar and move 'disk' and 'disks' to

#GP fault even though the I/O bitmap allowed access to those ports.

Here, "suitably endowed" means that the System Control Coprocessor
(#15) has Performance Monitoring Registers, including a CCNT (Cycle
Count) register.
The CCNT register is used in a way similar to the TSC register in
x86 processors by the get_cyclecount(9) function. The entropy-harvesting
thread is a heavy user of this function, and will benefit from not
having to call binuptime(9) instead.
One problem with the CCNT register is that it is 32-bit only, so
the upper 32-bits of the returned number are always 0. The entropy
harvester does not care, but in case any one else does, follow-up
work may include an interrup trap to increment an upper-32-bit
counter on CCNT overflow.
Another problem is that the CCNT register is not readable in user-mode
code; in can be made readable by userland, but then it is also
writable, and so is a good chunk of the PMU system. For that reason,
the CCNT is not enabled for user-mode access in this commit.
Like the x86, there is one CCNT per core, so they don't all run in
perfect sync.

Some of the translators use D functions that are not present in version
1.0 (e.g. inet_ntoa()) which can result in libdtrace crashing when running
scripts that restrict themselves to version 1.0

This first step is mostly to prevent the code from rotting even further
and to ensure these do not get wiped when fmake's code is removed from
the tree.
These tests are currently being skipped because they detect the underlying
make is not fmake and thus disable themselves -- and the reason is that
some of the tests fail, possibly due to legitimate bugs. Enabling them to
run against bmake will come separately.
Lastly, it would be ideal if these tests were fed upstream but they are
not ready for that yet. In the interim, just put them under usr.bin/bmake/
while we sort things out. The existence of a different unit-tests directory
within here makes me feel less guilty about this.

and 3.4 to generate dependency files for the '.inc.h' files generated
from .td files, and .sinclude those dependency files in clang.build.mk.
This will make future incremental builds of lib/clang and usr.bin/clang
work correctly, whenever any of the .td files get modified.
Note that this will not fix any problems with incremental builds from
*before* this revision, since there will not yet be any generated
dependency files. A quick workaround is to run the following:
find /usr/obj -type f -name '*.inc.h' | xargs rm
and then a regular incremental buildworld (e.g. with -DNO_CLEAN).

parent and child processes. Previously, we copied these pages even though
they are read only. However, the reason for copying them is historical and
no longer exists. In recent times, vm_map_protect() has developed the
ability to copy pages when write access is added to wired copy-on-write
pages. So, in this case, copy-on-write sharing of wired pages is not to be
feared. It is not going to lead to copy-on-write faults on wired memory.
