machine/regnum.h ends up being included by sys/procfs.h and sys/ptrace.h via
machine/reg.h. Many of the regnum definitions are too short and too generic
to be exposing to any userland application including one of these two
headers. Moreover, these actively cause build failures in googletest
(template <typename T1 ...> expanding to template <typename 9 ...>).
Hide the definitions behind _KERNEL or _WANT_MIPS_REGNUM, and patch all of
the userland consumers to define as needed.

load and people who pull in nvme/nvd from modules can't load nvd.ko
since it depends on nvme, not nvme_foo. The duplicate doesn't matter
since kldxref properly handles that case.
Turn off bus master after we detach the device (to match the prior
order). Release MSI after we're done detaching and have turned off
all the interrupts. Otherwise this may cause problems as other threads
race nvme_detach. This more closely matches the old order.

After r351243 when ALTQ was enabled in the kernel, the inline functions

Given usb_ethernet.h already includes all the various headers (which)
is the cause of the problem here, add if_var.h to it. This fixes the

Without this patch, when an application performed lseek(SEEK_DATA/SEEK_HOLE)
on a file in a file system that does not have its own VOP_IOCTL(), the
lseek(2) fails with errno ENOTTY. This didn't seem appropriate, since
ENOTTY is not listed as an error return by either the lseek(2) man page
nor the POSIX draft for lseek(2).
This was discussed on freebsd-current@ here:
http://docs.FreeBSD.org/cgi/mid.cgi?CAOtMX2iiQdv1+15e1N_r7V6aCx_VqAJCTP1AW+qs3Yg7sPg9wA

This streams out an XML document over several GDB packets describing all
threads in the system; their ids, name, and any loosely defined "extra info"
we feel like including. For now, I have included a string version of the run
state, similar to some of the DDB logic to stringify thread state.
The benefit of supporting this in addition to the qfThreadInfo/qsThreadInfo
packing is that in this mode, the host gdb does not ask for every thread's
"qThreadExtraInfo," saving per-thread round-trips on "info threads."
To use this feature, (k)gdb needs to be built with the --with-expat option.
I would encourage enabling this option by default in our GDB port, if it is
not already.
Finally, there is another optional attribute you can specify per-thread
called a "handle." Handles are arbitrarily long sequences of bytes,
represented in the XML as hexadecimal. It is unclear to me how or if GDB
actually uses handles for anything. So I have left them out.
Specifically, use 'const' for the key passed to the 'setkey' method
and 'const' for the 'iv' passed to the 'reinit' method.

Intel has created RST and many laptops from vendors like Lenovo and Asus. It's a
mechanism for creating multiple boot devices under windows. It effectively hides
the nvme drive inside of the ahci controller. The details are supposed to be a
trade secret. However, there's a reverse engineered Linux driver, and this
implements similar operations to allow nvme drives to attach. The ahci driver
attaches nvme children that proxy the remapped resources to the child. nvme_ahci
is just like nvme_pci, except it doesn't do the PCI specific things. That's
moved into ahci where appropriate.
When the nvme drive is remapped, MSI-x interrupts aren't forwarded (the linux
driver doesn't know how to use this either). INTx interrupts are used
instead. This is suboptimal, but usually sufficient for the laptops these parts
are in.
This is based loosely on https://www.spinics.net/lists/linux-ide/msg53364.html
submitted, but not accepted by, Linux. It was written by Dan Williams. These
changes were written from scratch by Olivier Houchard.

If device is unplugged from the system (CSTS register reads return
0xffffffff), it makes no sense to send any more recovery requests or
expect any responses back. If there is a detach call in such state,
just stop all activity and free resources. If there is no detach
call (hot-plug is not supported), rely on normal timeout handling,
but when it trigger controller reset, do not wait for impossible and

With r349546, it is a responsibility of the writer to clear PIPE_DIRECTW
after pinned data has been read. In particular, once a reader has
drained this data, there is a small window where the pipe is empty but
PIPE_DIRECTW is set. pipe_poll() was using the presence of PIPE_DIRECTW
to determine whether to return POLLIN, so in this window it would
claim that data was available to read when this was not the case.
Fix this by modifying several checks for PIPE_DIRECTW to instead look
at the number of residual bytes in data pinned by a direct writer. In
some cases we really do want to check for PIPE_DIRECTW, since the
presence of this flag indicates that any attempt to write to the pipe
will block on the existing direct writer.

- Correct an always-true assertion: vm_page_dequeue() may be called
from the page allocator with the page unlocked. The assertion
m->order == VM_NFREEORDER simply tests whether the page has been
