[v3 0/5] KVM: irqfd consumer based on IRQ bypass manager

[Feng Wu <feng.wu@intel.com>]

This series is based on Eric's "https://lkml.org/lkml/2015/7/6/291".
Basically, I made the following chagnes:
- Some changes based on Alex's irq bypass manager
  v2: https://lkml.org/lkml/2015/7/16/810
- Correct some minor erros and typo
- Add something needed for posted-interrupts

Since this series contain the common part of posted-interrupts and
forwarded irq, we can go forward only when this series are finalized,
,it is in the critical path. Seems Eric is on vacations these days,
to speed up the process, I send out this new version, Eric, hope you
are not mind of this. :) If I made any mistakes, please correct me.
Thank you!

My new version of posted-interrupts patches work well based on this
series.
