but since we have no alternative at the moment...

'kern.cp_time'. For a live kernel it uses the sysctl. For a crashdump,
it first checks to see if the kernel has a 'cp_time' global symbol. If
it does, it uses that. If that doesn't work, when it uses the recently
added kvm_getmaxcpu(3) and kvm_getpcpu(3) routines to walk all the CPUs
and sum up their counters.

we free memory from underneath them.
This fixes an occasional panic I've been seeing in softclock() where a bad
pointer would be encountered when pushing DTrace hard.
The PCM's sound.h file only seems to include <sys/tty.h>, because
channel_if seems to require selinfo. Just replace it with
<sys/selinfo.h>.
There's no real problem with including <sys/tty.h> here, even with
MPSAFE TTY, but <sys/tty.h> is something that should be used by the TTY
layer, its driver and code that integrated it with the process tree.
32-bit compat libs on amd64 since -march=k8 may generate instructions
that are not implemented on Intel EM64T processors. Instead, use
a simpler set of default flags that should work on all amd64-capable
CPUs.

corresponding USAGE should be skipped as well.
For example, below is a report desc fragment of some mouse:
COLLECTION
...
USAGE TWHEEL
FEATURE ...
...
USAGE WHEEL
INPUT ...
...
END COLLECTION
"USAGE TWHEEL" should be consumed after the FEATURE item is skipped,
otherwise, the INPUT item will be assigned to "USAGE TWHEEL" later,
other than "USAGE WHEEL".

In order to CATER this, DDB buffered output can be choosen at compile
time through the option DDB_BUFR_SIZE=nbytes where nbytes choose the size
of the buffer (suggested size is 128 bytes), which should be manually
specified in any interested config file.

It turns out I forgot to mention that people really need to make sure
their hints are up to date if they are updating a system through the
serial console.

kernel gs base, because %rip is adjusted only on kernel-mode trap caused
by iretq execution. On the other hand, the stack contains (hardware
part of) trap frame from the usermode. As a consequence, checking for
frame mode and doing swapgs causes the kernel to enter trap() with
usermode gs base.
Remove the check for mode and conditional swapgs, we already have right
gs base in the MSR.
