The first 10 patches in this set were posted earlier[1] and don't have any significant changes since then. This set sanitizes cpu/chip id to VAS id mapping, improves vas_win_close() performance and adds a check for return of credits and cleans up some code.
Patch 11 adds debugfs support for the VAS window contexts. Patches 11-18 add support for user space aka Fast thread-wakeup windows in VAS. These include a patch from Michael Neuling to support emulating the paste instruction.
