Set promiscuous code was unconditionally turning off multicast when
turning off promiscuous mode, this should only be done when there are
less than MAX groups. Thanks to Mike Karels for this correction.
Second, the overtmp interrupt setup/detection was wrong, correcting it.

- Clear code that workarounded a bug in FreeBSD 3,
and even predated import of netgraph(4).
- Clear workaround for m_nextpkt pointing into
next record in buffer (fixed in r248884).
Assert that m_nextpkt is clear.
- Do not rely on SOCK_STREAM sockets containing
M_PKTHDR mbufs. Create a header ourselves and
attach chain to it. This is correct fix for
kern/154676.

Use it to iterate over the lists of ada and da periphs when flushing caches

Change the default compiler for little-endian ARM to clang to allow for more
testing before 10.0 is released. As LLVM and clang currnetly lack support
for big-endian ARM leave gcc as the default there.
This will also allow us to investigate moving to use the hard floating-point
version of the ARM EABI on SoCs that include the Vector Floating Point unit.
A version of this is included in all ARMv6 and ARMv7 SoCs we currently, and
are likely to support.
Both the current ABI and the new EABI are supported by clang and it will be
built correctly depending on which is selected by the user.

This implements the kernel glue needed (getc, putc, rxready).
This isn't a 16550 UART, even if the datasheet overview claims so.
The Linux ar933x support was used as a reference, however the uart code
is a reimplementation.
Attentive viewers will note that the uart code is based off of the ns8250
code and the UART bus code is a stubbed-out version of this. I'll be
replacing it with non-stubbed versions soon, making this a fully featured
driver.
Tested:
* AP121 reference board (AR933x), booting through the mountroot> prompt;
then doing some basic interactive tests in ddb.
0x3C: /* Per Intel document 325462-045US 01/2013. */
Add manpage to document all the goodness that is available in this
processor model.

When looking up the absolute path for a kld, call find_kld_path() first.
This enables locating the module in a different directory than the one
stored in kernel memory.
With this change, kgdb can now be run on a kernel & vmcore whose associated
modules are located in the same directory as the kernel. This makes
independent triaging of problems much easier.
This change also does not break the normal kgdb use case where no arguments
are specified; in that case kgdb loads the running kernel and its modules.

1. If we wanted to send exactly as many bytes as the socket buffer is
sized for, the inner loop of kern_sendfile() would see that the
socket is full before seeing that it had no more bytes left to send.
This would cause it to return EAGAIN to the caller instead of
success. Fix by changing the order that these conditions are tested.
2. Simplify the calculation for the bytes to send in each iteration of
the inner loop of kern_sendfile()
3. Fix some calls with bogus arguments to sf_buf_ext(). These would
only trigger on mbuf allocation failure, but would be hilariously
bad if they did trigger.

Those requests are never unmapped now, but to be safe add respective check
there and allow unmapped I/O for the SIM by setting PIM_UNMAPPED flag.

With this in place the system reset path works, so 'reset' from kdb
actually resets the SoC.
