    Git branch : domain_hierarchy
    Last commit: 97d4ea1f0922fb47dd1b09cd2694b7fa5b519db9

Changes in V10 includes:
  * Remove the alloc_msi_irq and integrate into gicv2m_setup_msi_irq
  * Clean up the error_out logic in gicv2m_init_one
  * Add comments in gic_irq_domain_alloc()
  * Removed v2m_list since no longer needed with the irqdomain hierachy framework
  * Rename variable in gicv2m_taredown_msi_irq to be consistent with other functions
