handler and not more statically.
Unfortunately, it seems that this is not ideal for new platform bringup
and boot low level development (which needs ktr_cpumask to be effective
before tunables can be setup).
Because of this, add a way to statically initialize cpusets, by passing
an list of initializers, divided by commas. Also, provide a way to enforce
an all-set mask, for above mentioned initializers.
This imposes some differences on how KTR_CPUMASK is setup now as a
kernel option, and in particular this makes the words specifications
backward wrt. what is currently in -CURRENT. In order to avoid mismatches
between KTR_CPUMASK definition and other way to setup the mask
(tunable, sysctl) and to print it, change the ordering how
cpusetobj_print() and cpusetobj_scan() acquire the words belonging
to the set.
Please give a look to sys/conf/NOTES in order to understand how the
new format is supposed to work.
Also, ktr manpages will be updated shortly by gjb which volountereed
for this.
This patch won't be merged because it changes a POLA (at least
from the theoretical standpoint) and this is however a patch that
proves to be effective only in development environments.
