As usual, Ingo Molnar is in early with his changes for the various subsystems he maintains for the next kernel cycle. With Linux 3.19 being released last night, this morning are many pull requests from Ingo for Linux 3.20.

The changes going in through Ingo Molnar's branches aren't incredibly exciting this round, but it looks like the scheduler tree updates have the potential to be semi-exciting. In particular, the kernel scheduler changes have minor micro-optimizations, various fixes and enhancements, and a idle-poll handler fix that has the potential to result in power-savings.

Details on the scheduler feature pull for Linux 3.20 can be found via this mailing list pull request.

Aside from the scheduler work, the perf pull has support for AMD range break-points. Ingo's various x86-related pulls don't seem to have much in the way of changes exciting to end-users for Linux 3.20.
