Subject: [PATCH 0/6] Implement generic IPI support mechanism

This RFC series attempts to implement a generic IPI layer for reserving and sending IPI.

It is based on the discussion in this link

	https://lkml.org/lkml/2015/8/26/713

This series deals with points #1 and #2 only. Since I'm not the irq expert, I'm hoping this
series will give me early feedback and drive the discussion further about any potential
tricky points.

I tried to keep changes clean and small, but since this is just an RFC I might have missed
few things.

Thomas I hope I didn't stray far from what you had in mind :-)

My only testing so far is having SMP linux booting.

Qais Yousef (6):
  irqdomain: add new IRQ_DOMAIN_FLAGS_IPI
  irqdomain: add a new send_ipi() to irq_domain_ops
  irqdomain: add struct irq_hwcfg and helper functions
  irq: add a new generic IPI handling code to irq core
  irqchip: mips-gic: add a IPI hierarchy domain
  irqchip: mips-gic: use the new generic IPI API
