* ARM: kvm: rename cpu_reset to avoid name clashOlof Johansson2013-09-241-3/+3
| | | | | | | | | cpu_reset is already #defined in <asm/proc-fns.h> as processor.reset, so it expands here and causes problems. Cc: <stable@vger.kernel.org> Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org>
* ARM: KVM: Work around older compiler bugChristoffer Dall2013-08-301-1/+1
| | | | | | | | | | | | | | 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.

* ARM: KVM: Allow host virt timer irq to be different from guest timer virt irqAnup Patel2013-06-261-0/+12
| | | | | | | | | | | | | 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.

* KVM: ARM: Initial skeleton to compile KVM supportChristoffer Dall2013-01-231-0/+74
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.
