Subject: [RFC PATCH 0/3] arm: Some IPI injection optimization

This series optimize arm IPI injection process by making use of
ICC_SGI1R IRM bit and implementing gic_ipi_send_single().

Jingyi Wang (3):
  irqchip/gic-v3: Make use of ICC_SGI1R IRM bit
  irqchip/gic-v3: Implement gic_ipi_send_single()
  arm/arm64: Use gic_ipi_send_single() to inject single IPI
