Contact the list, look at the RFC, or look at the diff for how to do this. Sorry for the early commit of this, but I wanted to get it in today (per RFC) and didn't know if I would have a chance later today. This commit was SVN r18381.

* Processor affinity for Linux.
|
|
*
|
|
* Linux sucks. There are at least 3 different ways that
|
|
* sched_setaffinity is implemented.
|
|
*
|
|
* Fortunately we have an independent project called Portable Linux
|
|
* Processor Affinity (PLPA) which allows us to do processor affinity
|
|
* without knowing which flavor of afffinity is installed on the
|
|
* system a priori - PLPA does a few probes behind the scenes and
|
|
* utilizes the correct syntax to the correct system call to set
|
|
* or get processor affinity for us.
