Extending lwpsinfo_t with pr_lgrp for DTrace consumers
The sched provider defines the stable "lgrp" variable that is the lgroup of
the current CPU. This is mostly interesting when we can compare it with the
actual thread home lgroup, so I''d like to extend the lwpsinfo_t structure with
the new pr_lgrp field which will be implemented using translator. This will
match the addition...

Dtrace starts very slowly on T5440
Hi all,
We just got a shiny new T5440, and one of the first things I noticed
(besides the insane number of hardware contexts), is that dtrace takes
30 seconds to a minute to fire up scripts with 5-6 probes, where our
T5220 usually takes under a second. Shutdown is similar, though slightly
faster.
This is mostly annoying because it takes so long to attach that it''s
hard to tell when
