Hello, This small series deals with some weirdness in the mechanism with which the credit scheduler choses what PCPU to tickle upon a VCPU wake-up. Details are available in the changelog of the first patch. The new approach has been extensively benchmarked and proved itself either beneficial or harmless. That means it does not introduce any significant amount of overhead and/or performances

...ession. The two things are related anwyay: the reason you now need scheduling locks around EDOM_INFO variables is because you''re getting rid of the pausing and the lock in schedule.c.

The following series flushes my documentation queue and replaces previous postings of those patches. The main difference is that the xl cfg file is now formatted using POD instead of markdown and presented as a manpage. I have setup a cron job to build docs/html and publish it at http://xenbits.xen.org/docs/unstable/ (it''s a bit bare right now). The motivation for some of these patches
