and voltage sensor, TWSI is used to get sensor data. msk(4) does
not monitor these sensors and interrupt for TWSI completion is
disabled by default.
However, due to unknown reason, the TWSI completion interrupt fires
and it resulted in interrupt storm. To fix it, acknowledges the
TWSI completion interrupt if driver see the event. Given that not
all Yukon II controllers show the issue it could be a silicon bug
which does not honor interrupt masking.
Probably the right way to address the issue is disabling automatic
TWSI cycle initiation against these sensors. It would be even
better to implement reading voltage/temperature from the NIC but it
requires access to National LM80 through TWSI and documentation to
do that is not available yet(probably will never happen).

libraries to use thread ids directly, without slow and verbose conversion
of thread id into pid.
The PGET_NOTID flag is provided to allow a specific sysctl to disallow
this behaviour. All current callers of pget(9) have useful semantic to
operate on tid and do not need this flag.
