driver could be the active timecounter, leading to recursion during mutex
profiling, but the atrtc driver cannot be a timecounter, so it isn't needed.

This should partially solve the problem, when setkey(8) returns
EAGAIN error on systems with many SAs or SPs.

o count in_nomem counter when we have failed to allocate mbuf for
promisc socket;
o count in_msgtarget counter when we have secussfully sent data to socket;
o Since we are sending messages in a loop, returning error on first fail
interrupts the loop, and all remaining sockets will not receive this
message. So, do not return error when we have failed to send data to ALL
or REGISTERED target. Return error only for KEY_SENDUP_ONE case. Now,
when some socket has overfilled its receive buffer, this will not break
other sockets.

un-function-like RTC_LOCK/UNLOCK macro usage into normal function calls.
Since there is no longer any need to handle register access from a debugger
context, those function calls can just be regular mutex lock/unlock calls.

command handler which provided much the same information. Removing the
possibility of accessing the hardware regs from the debugger context
paves the way for simplifying the locking code in the driver.
Nothing uses the #define's values or the types. (Some NTP code does use
an audio_info_t, but it is in #ifdef'd support for Solaris and is not
this audio_info_t).

uvolt: Current value
always_on: 1 If the reg is always on
boot_on: 1 If the reg is set at boot time
enable_cnt: Number of consumer(s)
enable_delay: Delay before enabling the regulator
ramp_delay: The Ramp delay
max_uamp: The maximum value of the regulator in uAmps
min_uamp: The minimal value of the regulator in uAmps
max_uvolt: The maximum value of the regulator in uVolts
min_uvolt: The minimal value of the regulator in uVolts

These parameters may be changed via ifconfig(8); by default,
mgt / mcast rates are lowest possible and ucast rate is not set
(matches previous configuration).
While here, store some variables locally for better readability.
The vfs.mountroot.timeout tunable and .timeout directive in a mount.conf(5)
file allow specifying a wait timeout for the device(s) hosting the root
filesystem to become usable. The current mechanism for waiting for devices
and detecting their availability can't be used for zfs-hosted filesystems.
See the comment #20 in the PR for some expanded detail on these points.
This change adds retry logic to the actual root filesystem mount. That is,
insted of relying on device availability using device name lookups, it uses
the kernel_mount() call itself to detect whether the filesystem can be
mounted, and loops until it succeeds or the configured timeout is exceeded.
These changes are based on the patch attached to the PR, but it's rewritten
enough that all mistakes belong to me.

Upstream DTBs don't provide IRQ lines for the RNG. Moreover, harvesting
bytes as often as the RNG interrupt is triggered (87 times per sec) is an
overkill.
For these reasons, get rid of the interrupt mode and make callout mode the
default, with random bits harvested every 4 seconds.

If tftpd receives a command with an unknown opcode, it simply exits 1. It
doesn't send an ERROR packet, and the client will hang waiting for one. Fix
it.
PR: 226005
MFC after: 3 weeks
On a WRQ (write request) tftpd checks whether the client has access
permission for the file in question. If not, then the write is prevented.
However, tftpd doesn't reply with an ERROR packet, nor does it abort.
Instead, it tries to receive the packet anyway.
The symptom is slightly different depending on the nature of the error. If
the target file is nonexistent and tftpd lacks permission to create it, then
tftpd will willingly receive the file, but not write it anywhere. If the
file exists but is not writable, then tftpd will fail to ACK to WRQ.

tftpd(8) says that files may only be written if they already exist and are
publicly writable. tftpd.c verifies that a file is publicly writable if it
uses an absolute pathname. However, if the pathname is relative, that check
is skipped. Fix it.
Note that this is not a security vulnerability, because the transfer
ultimately doesn't work unless the file already exists and is owned by user
nobody. Also, this bug does not affect the default configuration, because
the default uses the "-s" option which makes all pathnames absolute.

Apply patch submitted with PR 217159 to make ps use unlimited

This change was requested to work around lack of -ww in scripts from
third-party packages, including Hadoop, and adds a small measure of
Linux compatibility. Hopefully few if any non-interactive scripts
depend on the old default of 79.

Most sysctl nodes only return a single value, but some nodes return an
array of values (e.g. kern.cp_time). sysctl(8) understand how to display
the values of a node that returns multiple values (it prints out each
numeric value separated by spaces). However, until now sysctl(8) has
only been able to set sysctl nodes to a single value. This change
allows sysctl to accept a new value for a numeric sysctl node that contains
multiple values separated by either spaces or commas. sysctl(8) parses
this list into an array of values and passes the array as the "new" value
to sysctl(2).

On an RRQ, tftpd doesn't exit as soon as it's finished receiving a file.
Instead, it waits five seconds just in case the client didn't receive the
server's last ACK and decides to resend the final DATA packet.
Unfortunately, this created a 5 second delay from when the client thinks
it's done sending the file, and when the file is available for other
processes.
Fix this bug by closing the file as soon as receipt is finished.
