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.

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
