Sort of a port from freebsd, but I had to write all the interesting bits
myself. Not very complete yet, but good enough to commit over.

extension to the GIC controller, which is represented as subnode in the
device tree. There can be multiple GICv2Ms, so it makes sense to attach
those to ampintc(4) as some kind of simplebus. The GICv2M is simply an
interrupt generator that can be used by PCIe devices to ring the door
bell. There is no need for further configuration, we only need to find
out which SPIs we are allowed to use for MSI and to register an edge
triggered interrupt on a (randomly) allocated SPI.
Implement support for interrupt types. The GIC only seems to support
level triggered active-high or egdge triggered low-to-high interrupts.
We currently always configure them to be level triggered, which is a
sane default for most controllers. Since MSI interupts on the GIC are
edge triggered, we need to be able to parse the type information and to
configure the interrupt correspondingly.

the memory in uvm. Another process could use the false 0 then. To
be on the safe side, protect all access to ku_indx and ku_pagecnt
with a mutex. Update ku_indx and ku_pagecnt before calling
uvm_km_free(). Update ksp after uvm_km_free() to keep accounting
correct.

to ioctl(TIOCSPGRP). The ioctl handlers expect a pointer to an int, so
read the argument into a local int variable and pass the variable's
address to the handler instead of referencing SCARG(uap, arg) directly.

VOP_SETATTR() does not release the vnode lock (and it has never done
the unlocking in the past). Therefore spec_setattr() has to keep the
argument vnode locked and unlock v_specparent instead after the nested
VOP_SETATTR() call.
Fixes a WITNESS panic found by anton@

error that would happen otherwise when a traced and stopped
multithreaded process is forced to exit. The error shows up as a kernel
panic when WITNESS is enabled. Without WITNESS, the error causes
a system hang.
sched_exit() has expected that a single KERNEL_UNLOCK() would release
the lock completely. That assumption is wrong when an exit happens
through the signal tracing logic:
sched_exit
exit1
single_thread_check
single_thread_set
issignal <-- KERNEL_LOCK()
userret <-- KERNEL_LOCK()
syscall
The error is a regression of r1.216 of kern_sig.c.

Those devices have a broken AudioControl descriptor which advertises a
bad value for bLength for the FEATURE_UNIT sub-descriptor, so add a
quirk 'fixing' this bLength so that uaudio(4) attaches properly instead
of bailing out with 'audio descriptors make no sense, error=4'.
My C310 now properly attaches but doesnt seem to work right now, this is
a different issue that will be worked on.

establish function parses the device tree's interrupt map to discover
the correct interrupt controller node and interrupt cells for the given
PCI node. After retrieving that information we can do the same the
normal FDT establish API already does.
MSI interrupts are established in a different way as well. Instead of
simply hooking up the interrupt handler and returning an MD cookie, we
need to pass back information for the PCI controller to configure its
interrupt correctly. For this, add another establish routine into the
FDT-based interrupt API which looks up msi-controller nodes and calls
their MSI-specific establish function if requested.
