Christoffer Dall 6833d83891 ARM: KVM: Work around older compiler bug
Compilers before 4.6 do not behave well with unnamed fields in structure
initializers and therefore produces build errors:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10676

By refering to the unnamed union using braces, both older and newer
compilers produce the same result.

Anup Patel 5ae7f87a56 ARM: KVM: Allow host virt timer irq to be different from guest timer virt irq
The arch_timer irq numbers (or PPI numbers) are implementation dependent,
so the host virtual timer irq number can be different from guest virtual
timer irq number.

This patch ensures that host virtual timer irq number is read from DTB and
guest virtual timer irq is determined based on vcpu target type.

Christoffer Dall 749cf76c5a KVM: ARM: Initial skeleton to compile KVM support
Targets KVM support for Cortex A-15 processors.

Contains all the framework components, make files, header files, some
tracing functionality, and basic user space API.

Only supported core is Cortex-A15 for now.

Most functionality is in arch/arm/kvm/* or arch/arm/include/asm/kvm_*.h.
