r264114 by davidxu:
Fix SIGIO delivery. Use fsetown() to handle file descriptor owner
ioctl and use pgsigio() to send SIGIO.
r264310 by davidxu:
Add kqueue support for devctl.
r268570:
Clear nonblock and async on devctl close instaed of open.
This is a purely cosmetic change.
proc exit: don't take PROC_LOCK while freeing rlimits
Code wishing to check rlimits of some process should check whether it
is exiting first, which current consumers do.
Avoid relocking filedesc lock when closing fds during fdp destruction.
Don't call bzero nor fdunused from fdfree for such cases. It would do
unnecessary work and complain that the lock is not taken.
=======
Don't zero fd_nfiles during fdp destruction.
Code trying to take a look has to check fd_refcnt and it is 0 by that time.
This is a follow up to r268505, without this the code would leak memory for
tables bigger than the default.
Perform a lockless check in sigacts_shared.
It is used only during execve (i.e. singlethreaded), so there is no fear
of returning 'not shared' which soon becomes 'shared'.
While here reorganize the code a little to avoid proc lock/unlock in
shared case.
Use a separate variable for resource id, because 'i' may increment at a
rate greater than 1 on each iteration.
Handle various ways that interrupt config data can be malformed by
warning and assuming more or less reasonable values.
Cache the imx6 SoC type in a static var so that it only has to be figured
out by sniffing hardware registers once.
Add a missing clock register definition.
Set ofwbus and simplebus to attach during BUS_PASS_BUS.
Define names that drivers can use to adjust their position relative to
other drivers within a BUS_PASS
Adjust ofwbus and simplebus to attach at BUS_PASS_ORDER_MIDDLE, so that
a platform can attach some other bus first if necessary.
Set the pl310 L2 cache driver to attach during the middle of BUS_PASS_CPU.
Attach arm generic interrupt and timer drivers in the middle of
BUS_PASS_INTERRUPT and BUS_PASS_TIMER, respectively.
Add an arm option, ARM_DEVICE_MULTIPASS, used to opt-in to multi-pass
device attachment on arm platforms. If this is defined, nexus attaches
early in BUS_PASS_BUS, and other busses and devices attach later, in the
pass number they are set up for. Without it defined, nexus attaches in
BUS_PASS_DEFAULT and thus so does everything else, which is status quo.
Turn on interrupt window exiting unconditionally when an ExtINT is being
injected into the guest.
Add helper functions to populate VM exit information for rendezvous and
astpending exits.
Provide APIs to directly get 'lowmem' and 'highmem' size directly.
Expose the amount of resident and wired memory from the guest's vmspace
Add ioctl(VM_REINIT) to reinitialize the virtual machine state maintained
by vmm.ko. This allows the virtual machine to be restarted without having
to destroy it first.
Merge if_nf10bmac(4), a driver to support an NetFPGA-10G Embedded
CPU Ethernet Core.
The current version operates on a simple PIO based interface connected
to a NetFPGA-10G port.
To avoid confusion: this driver operates on a CPU running on the FPGA,
e.g. BERI/mips, and is not suited for the PCI host interface.
Adjust the register layout to allow for 64bit registers in the
future for nf10bmac(4). Also, add support for and enable RX interrupts.
Allow switching between 32bit and 64bit bus width data access at compile
time by setting NF10BMAC_64BIT and using a REGWTYPE #define to set correct
variable and return value widths.
Adjust comments to indicate the 32 or 64bit register widths.

For BERI on NetFPGA assume HZ=100 by default.
Remove the uart support in favour of a "jtag-uart" interface imitation
providing a much simpler interface, directly exported to the host,
allowing the toolchain to be shared with BERI on Altera. [1]

Based on xlp_machdep.c and completed the list of options based on
boot/mips/beri/loader/metadata.c allow FDT configuration to set
command line options.
This leads to an interesting quesiton of future interactions with loader.
However for configurations without loader this allows bootverbose or boot
single user to be set by compiling a new kernel, which is good enough for
testing and debugging.

When switching variables to flags in r243185 a few cases were missed.
After r263152 (in head) this leaves unused variables if route(8) is
compiled without INET support.
Switch the remaining variable accesses to flags and remove now obsolete
variables.

Bite the bullet and start removing the first compile time warnings
by removing unsued file local functions and then unused callees.
A lot more warnings to resolve but someone had to break the ice.
X-Comment: I am not the new maintainer; chime in, it's ours.
Use feature_present(3) to determine whether to open an INET or an
INET6 socket when needed to allow pfctl to work on noinet and noinet6
kernels (and try to provide a fallback using AF_LINK as best effort).
Adjust the Makefile to also respect relevant src.conf(5) options
for compile time decisions on INET and INET6 support.

Correct warnings comparing unsigned variables < 0 constantly reported

Provide -o vers= support for mount_nfs.
Our mount_nfs does use -o nfsv<2|3|4> or -2 or -3 to specify the version.
OSX (these days), Solaris, and Linux use -o vers=<2,3,4>.
With the upcoming autofs support we can make a lot of (entrerprisy) setups
getting mount options from LDAP just work by providing -o vers= compatibility.

fparseln(3): Update from NetBSD sources.
-fix a condition so that fparseln() doesn't report spurious empty lines

-no escape character means no escaped characters
modify the previous fix so that no pointless realloc()s are done in
the case of multiple empty continuation lines, and comment the code
to make the logics obvious.
fparseln is now part of libc in NetBSD so this changes the previous

The journal is only prepared to handle full-size block numbers, so we
have to adjust freeblk records to reflect the change to a full-size block.
For example, suppose we have a block made up of fragments 8-15 and
want to free its last two fragments. We are given a request that says:
FREEBLK ino=5, blkno=14, lbn=0, frags=2, oldfrags=0
where frags are the number of frags to free and oldfrags are the number
of fragments to keep. To block align it, we have to change it to have a
valid full-size blkno, so it becomes:
FREEBLK ino=5, blkno=8, lbn=0, frags=2, oldfrags=6
