bcm2835_virtgpio: Add driver for virtual GPIO controller on some RPi models
This driver enables bcm2835-virtgpio GPIO controller found on RPi3B and
some CM boards. On which, the ACT (green) LED is connected to this
controller. It is essential for FreeBSD to have this driver to control
this LED.
It will be exposed via gpioled(4).

rss: make toeplitz.c standard part of the kernel
This will fix LINT-NOIP build. This actually adds very little to the
kernel text, e.g. 500 bytes on amd64. A perfect solution would be to
instead declare rss_config.c as 'optional inet | inet6', but that would
fail to build LINT-NOIP in several NIC drivers, that use RSS and
absolutely ignore that both INET and INET6 are optional. It is very
unlikely that vendors who maintain these drivers will will ever chase the
holy grail of a build that doesn't support IPv4 and IPv6.

sbuf: make assertion message a lot more useable
Saying that we are called with an (un)finished or corrupted sbuf
is like saying "error" (though [un]finished is an extra hint).
Add the pointer to the sbuf so one could easily check it,
add the flags we are checking so one could see quickly about
a possible state mismatch.
Given we already dereference the pointer in the KASSERT there is no
extra harm adding it to the message.

vmm: Move common accessors and vm_eventinfo into sys/dev/vmm
Now that struct vm and struct vcpu are defined in headers, provide
inline accessors. We could just remove the accessors outright, but they
don't hurt and it would result in unneeded churn.
As a part of this, consolidate definitions related to struct
vm_eventinfo as well. I'm not sure if struct vm_eventinfo is really
needed anymore, now that vmmops_run implementations can directly access
vm and vcpu fields, but this can be resolved later.
No functional change intended.

divert: Use a better source identifier for netisr_queue_src() calls
These opaque IDs are used by netisr to distribute work among threads.
The mapping function is simply SourceID % numthreads, so using socket
addresses as source IDs isn't going to distribute packets well due to
alignment.
Use the divert socket's generation number instead, as that suits this
purpose much better.

nullfs: Fix handling of doomed vnodes in nullfs_unlink_lowervp()
nullfs_unlink_lowervp() is called with the lower vnode locked, so the
nullfs vnode is locked too. The following can occur:
1. the vunref() call decrements the usecount 2->1,
2. a different thread calls vrele() on the vnode, decrements the
usecount 0->1, then blocks on the vnode lock,
3. the first thread tests vp->v_usecount == 0 and observes that it is
true,
4. the first thread incorrectly unlocks the lower vnode.
Fix this by testing VN_IS_DOOMED directly. Since
nullfs_unlink_lowervp() holds the vnode lock, the value of the
VIRF_DOOMED flag is stable.
Thanks to leres@ for patiently helping to track this down.

vmm: Consolidate vm and vcpu definitions
There is quite a lot of duplication of code between amd64, arm64 and
riscv with respect to VM and vCPU state management. This is a bit
tricky to resolve since struct vm and struct vcpu are private to vmm.c
and both structures contain a mix of machine-dependent and
machine-independent fields.
To allow deduplication without also introducing a lot of churn, follow
the approach of struct pcpu and 1) lift the definitions of those
structures into a new header, sys/dev/vmm/vmm_vm.h, and 2) define
machine-dependent macros, VMM_VM_MD_FIELDS and VMM_VCPU_MD_FIELDS which
lay out the machine-dependent fields.
One disadvantage of this approach is that the two structures are no
longer private to vmm.c, but I think this is acceptable.
No functional change intended. A follow-up change will move a good deal
of machine/vmm/vmm.c into sys/dev/vmm/vmm_vm.c.

buf: Relax an assertion in BUF_UNLOCK
The BUF_UNLOCK macro asserts that B_REMFREE is not set, as it is up to
the lock owner to complete the dequeue from the free list before
releasing the lock. However, if the thread has acquired the lock
multiple times, then releasing the recursive lock should be ok. Modify
the assertion to reflect this.
This was triggered by an out-of-tree filesystem.
