The VGIC distributor struct has a number of fields which are named
subopimally when needing to add more refined handling of level-triggered
interrupts.
We also never handled writes to the GICD_ISPENDRn and GICD_ICPENDRn
properly, which was never a real concern until we started playing with
IRQ injection for assigned devices, IRQFDs, and other fun stuff.
This series tries to address some of these issues.
The code is also available here:
git://git.linaro.org/people/christoffer.dall/linux-kvm-arm.git vgic-set-clear-pending-v2
Changelog[v2]:
- Rebased onto Marc's series from hell (kvm-arm/debug-merge-3.17)
- Clarify comment in vgic_process_maintenance()
- Fix spelling errors and other commit text blurbs
- Actually tested it this time around (on TC2 and APM Mustang)
