Fixed build on > non-ARM-Linux hosts > > v5 => v6 > - Fixed various checkpatch.pl style warnings > - Removed TODO in gicv3_init_irqs_and_mmio(), relevant memory API patch > included > - gicv3_init_irqs_and_mmio() now takes 3 arguments instead of 4.

Avoids code duplication. > - Do not add NULL msi-parent phandle to PCI device in the FDT > - Removed a couple of stale things from virt.c > > v3 => v4 > - Fixed stupid build breakage in patch 0002 > - Rebased on top of current master, patch 0003 adjusted according to > kvm_irqchip_create() changes > - Added assertion against uninitialized kernel_irqchip_type > - Removed kernel_irqchip_type initialization from models which do not > use KVM vGIC > > v2 => v3 > - Removed some unrelated and unnecessary changes from virt machine, > occasionally slipped in; some of them caused qemu to crash on ARM32. > - Fixed build for ARM32; vGICv3 code requires definitions which are > present only in ARM64 kernel > > v1 => v2 > - Base class included, taken from the series by Shlomo Pongratz: > http://lists.nongnu.org/archive/html/qemu-devel/2015-06/msg01512.html > The code is refactored as little as possible in order to simplify > further addition of software emulation: > - Minor fixes in code style and comments, according to old reviews > - Removed REV_V3 definition because it's currently not used, and it does > not add any meaning to number 3. > - Removed reserved regions for MBI and ITS (except for 'virt' machine > memory map).
