to recreate it from ${MAKEOBJDIRPREFIX} and ${SRC_BASE} and ${KERNCONF},
the latter being especially problematic when KERNCONF is set to the names
of multiple kernel configs.
I don't yet know which RX descriptor bits map to shortgi, long-gi,
short-preamble, long-preamble, STBC, LDPC, HT40, etc - so I can't
easily add those just yet.
There's apparently no per-frame RX RSSI information exposed so we
also just use the results from the previous calibration task.
This also tidies up how the per-mbuf RSSI is pushed into the frame -
now that it's attached to the mbuf via rx_stats, we don't have to
do any silly hijinx to get it out of the frame processing path.

dump_avail[] is supposed to be a superset of phys_avail[] that
describes all of the memory ranges that should be included in a full
dump. minidumps don't consider pages described by dump_avail[] to be
valid and thus they are excluded via the is_dumpable() function. Most
MIPS platforms (including MALTA) set dump_avail[] to be identical to
phys_avail[]. In particular, phys_avail[] doesn't include the kernel
itself, so pages for the kernel and it's global variables are not
considered dumpable and not included in the dump. Fix this by setting
dump_avail[0] to the first memory address (0) rather than the end of
the kernel.
Several other MIPS platforms have the same bug, though I am only able
to test malta in qemu. The correct fix is to set dump_avail[] to
describe RAM and in particular to not set dump_avail[0] to the end of
the kernel (kernel_kseg0_end).

The removal of TAILQ_FOREACH_SAFE introduced a small race: when the last
thread on a sleepqueue is awoken, it reclaims the sleepqueue and may begin
executing on a different CPU before sleepq_resume_thread() returns. This
leaves a window during which it may go back to sleep and incorrectly be
awoken again by the caller of sleepq_broadcast().

- Pass the correct object to unload_filtees().
- Use a marker to restart iteration after unload_filtees() has returned.
It calls dlclose() and may recursively remove entries from the global
object list, so TAILQ_FOREACH_SAFE is not sufficient.

Current Xen IPI setup functions require that the caller provide a device in
order to obtain the name of the interrupt from it. With early AP startup this
device is no longer available at the point where IPIs are bound, and a KASSERT
would trigger:
panic: NULL pcpu device_t
cpuid = 0
KDB: stack backtrace:
db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xffffffff82233a20
vpanic() at vpanic+0x186/frame 0xffffffff82233aa0
kassert_panic() at kassert_panic+0x126/frame 0xffffffff82233b10

mi_startup() at mi_startup+0x118/frame 0xffffffff82233b70
btext() at btext+0x2c
Fix this by no longer requiring the presence of a device in order to bind IPIs,
and simply use the "cpuX" format where X is the CPU identifier in order to
describe the interrupt.

VMware tries to enable this bit to avoid multiple threshold notifications
in case of multiple initiators connected to the same LUN. Unfortunately
their code sends MODE SELECT(6) request with parameter length hardcoded
for the page without any thresholds. Since we have four threshold and our
page is bigger, this attempt fails, that is correct in my understanding.
So all we can do about this now is to report proper error code and hope
VMware fix their code one day.

The libgcc __register_frame and __deregister_frame functions take a
pointer to a set of FDE/CIEs, terminated by an entry where length is 0.
In Apple's libunwind implementation the pointer is taken to be to a
single FDE. I suspect this was just an Apple bug, compensated by Apple-
specific code in LLVM.
See lib/ExecutionEngine/RuntimeDyld/RTDyldMemoryManager.cpp and
http://lists.llvm.org/pipermail/llvm-dev/2013-April/061737.html
for more detail.
This change is based on the LLVM RTDyldMemoryManager.cpp. It should
later be changed to be alignment-safe.

Now that we have our sysctl tree annotated with aggregation labels,
let's go ahead and provide a very simple utility for exporting the
sysctl tree in Prometheus' format. It can either be used in conjunction
with the Prometheus node exporter or run through inetd(8).
The reason why I'm opting for having it in the base system is because it
has a pretty strong integration with some of sysctl's innards, such as
access to iterators, name lookups, metadata and type information. As I
am investigating whether we can add histograms as native types to sysctl
as well, this integration will only get stronger as we go along. That's
why it would be safer to oversee the development of this exporter
ourselves, as opposed to having it as an external project.
This exporter is remarkably compact, especially when compared to the
official Linux binary of the Prometheus node exporter (16 KB vs 12 MB).
I guess this could be an interesting aspect for monitoring embedded
FreeBSD-based systems.
