e3480f19d0 Pin the right thread.
This _was_ right, a last minute suggestion and not enough testing makes
Adrian a bad boy.

Tested:

* igb(4) with RSS patches, by hand verifying each igb(4) taskqueue
  tid from procstat -ka using cpuset -g -t <tid>.

5ab6b9e5af Export two new settings for the AM335x PWM, the clock prescaler (clkdiv)
and the actual PWM frequency.

Enforce the maximum value for the period sysctl.

The frequency systcl now allows the direct setting of the PWM frequency (it
will try to find the better clkdiv and period for a given frequency, i.e.
the ones that will give the better PWM resolution).

This allows the use lower frequencies on the PWM.  Without changing the
clock prescaler the minimum PWM frequency was 1.52kHz.

PWM frequencies checked with an osciloscope.

PWM output tested with some R/C servos at 50Hz.

9c2a942387 Activate vcpus from bhyve(8) using the ioctl VM_ACTIVATE_CPU instead of doing
it implicitly in vmm.ko.

Add ioctl VM_GET_CPUS to get the current set of 'active' and 'suspended' cpus
and display them via /usr/sbin/bhyvectl using the "--get-active-cpus" and
"--get-suspended-cpus" options.

This is in preparation for being able to reset virtual machine state without
having to destroy and recreate it.

efb62c9bbe convert to using the _daddr_t types like newfs was...
Put the superblock in the correct possition for UFS2... There is a bug
in FFS that if we don't put it here (for UFS2), it will forcefully
relocate the superblock, and I believe cause data loss..

I have a fix for that, but w/ how many releases are broken, we won't be
able to switch to the better _FLOPPY (block 0) for this for a while..

f38753151f Glibc was switched to the FUTEX_WAIT_BITSET op and CLOCK_REALTIME
flag has been added instead of FUTEX_WAIT to replace the FUTEX_WAIT
logic which needs to do gettimeofday() calls before the futex syscall
to convert the absolute timeout to a relative timeout.
Before this the CLOCK_MONOTONIC used by the FUTEX_WAIT_BITSET op.

When the FUTEX_CLOCK_REALTIME is specified the timeout is an absolute
time, not a relative time. Rework futex_wait to handle this.
On the side fix the futex leak in error case and remove useless
parentheses.

Properly calculate the timeout for the CLOCK_MONOTONIC case.

b68345e32c Rework the notion of CPU used in top. In particular, for subsequent
displays after a pause, use the difference in runtime divided by the
length of the pause as the percentage of CPU used instead of the value
calculated by the kernel.  In addition, when determing if a process or
thread is idle or not, treat any process or thread that has used any
runtime or performed any context switches during the interval as busy.

Note that the percent CPU is calculated as a double and stored in an
array to avoid recalculating the value multiple times in the comparison
method used to sort processes in the CPU display.

0b964e71ba Enable a login console on ttyu0 by default if it is a serial console. This
prevents surprising effects post-installation on serial-only x86 systems
(e.g. bhyve) where the kernel messages will appear, rc scripts will run,
and then there will be no login prompt and you will be locked out of the
system.

Thanks to Devin Teske and Peter Grehan for ideas and testing. With this
patch, it may also be possible to unify all or most of the machine-specific
ttys files.
