Commit bf454ca88b made wg_transmit() defined only when "device netmap"
is configured, as if_wg's if_transmit implementation should never be
called otherwise, but this breaks a requirement that interfaces
implement both or neither of if_transmit and if_qflush.
Restore the old behaviour of unconditionally defining wg_transmit(). It
contains an assertion that the interface is in netmap mode.

d0941ed fixed an edge case invloving mlock() and superpage creation
by creating and inserting a leaf pagetable page for mlock'd superpages.
However, the code does not properly release the reference to the
pagetable page in the error handling path.
This commit fixes the issue by adding calls to 'pmap_abort_ptp'
in the error handling path.

This reverts commit 1a968da448.
I was mistakenly looking at the version strings in the CVS attic
but the function was moved to libc/stdio where it matches the
current string.
The allocation call could result in sleep lock violation if it is in
smp_rendezvous. Move it out. Also move the pcpu memory pointer to
vmbus_pcpu_data since it is only used on Hyper-V.

The lower layers implement a ABI compatible Linux ioctl for a few of the
Linux IOCTLs. Translate them and pass them down. Since they are ABI
compatible, just use the nvme ioctl name.

Add the NVME_IOCTL_ID, NVME_IOCTL_ADMIN_CMD, and NVME_IOCTL_IO_CMD Linux
compatible ioctls. These may be run on either an I/O (ns) dev or a nvme
(admin) dev. Linux allows both on either device, and programs use this
and aren't careful about having the right device open. Emulate this
feature, and implement these ioctls. The data is passed in into the
kernel in host byte order (not converted to le). Results are returned in
host order.
The timeout field is ignore, and the metadata and metadata_len fields
must be zero.
The addr field can be null, even when the data_len is non zero (FreeBSD's
ioctl interface prohibits this, Linux's just ignores the inconsistency).
Only the cdw10 is returned from the command: the status is not returned
in 'result' field. XXX need to verify that this is what Linux does on an
error signaled from the drive.
No external include file is yet available for this: most programs that
call this interface either use a linux-specific path <linux/nvme.h> or
have their own private copy of the data. It's unclear the best thing to
do.
Also, create a /dev/nvmeXnY as an alias for /dev/nvmeXnsY.
These changes allow a native build of nvme-cli to work for everything
that doesn't depend on sysfs entries in /sys, calls that use metadata,
send / receive drive data and sed functionality not in our nvme driver.

vm_phys_enq_chunk() inserts a run of pages into the buddy queues. When
lazy initialization is enabled, only the first page of each run is
initialized; vm_phys_enq_chunk() thus initializes the page following the
just-inserted run.
This fails to account for the possibility that the page following the
run doesn't belong to the segment. Handle that in vm_phys_enq_chunk().

Add some sanity checks when service jails are used in jails:
- children.max > 0
- children.max - children.cur > 0
The nesting is too deep at those places to have a sane formatting, so no
line wrapping at the usual column.
If someone has a better idea how to format this: feel free to go ahead.
Clarify that the "sysvipc" svcj option inherits from the host / parent.
Add "sysvipcnew" which creates a new SysV namespace for the service
jail.
Sanity check that only one of them is used.
Make it explicit why we must set the trap vector before enabling virtual
memory.
