2016-02-29ARM: KVM: Add vgic v2 save/restoreMarc Zyngier
This patch shouldn't exist, as we should be able to reuse the arm64 version for free. I'll get there eventually, but in the meantime I need an interrupt controller. Reviewed-by: Christoffer Dall <christoffer.dall@linaro.org> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2016-02-29ARM: KVM: Add timer save/restoreMarc Zyngier
This patch shouldn't exist, as we should be able to reuse the arm64 version for free. I'll get there eventually, but in the meantime I need a timer ticking. Reviewed-by: Christoffer Dall <christoffer.dall@linaro.org> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>

2016-02-29ARM: KVM: Add system register accessor macrosMarc Zyngier
In order to move system register (CP15, mostly) access to C code, add a few macros to facilitate this, and minimize the difference between 32 and 64bit CP15 registers. This will get heavily used in the following patches. Acked-by: Christoffer Dall <christoffer.dall@linaro.org> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2016-02-29ARM: KVM: Add a HYP-specific header fileMarc Zyngier
In order to expose the various HYP services that are private to the hypervisor, add a new hyp.h file. So far, it only contains mundane things such as section annotation and VA manipulation. Acked-by: Christoffer Dall <christoffer.dall@linaro.org> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2016-02-29ARM: KVM: Move GP registers into the CPU context structureMarc Zyngier
Continuing our rework of the CPU context, we now move the GP registers into the CPU context structure. Reviewed-by: Christoffer Dall <christoffer.dall@linaro.org> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2016-02-29ARM: KVM: Move CP15 array into the CPU context structureMarc Zyngier
Continuing our rework of the CPU context, we now move the CP15 array into the CPU context structure. As this causes quite a bit of churn, we introduce the vcpu_cp15() macro that abstract the location of the actual array. This will probably help next time we have to revisit that code.

2016-02-29ARM: KVM: Move VFP registers to a CPU context structureMarc Zyngier

2016-02-29ARM: KVM: Remove __kvm_hyp_code_start/__kvm_hyp_code_endMarc Zyngier
Now that we've unified the way we refer to the HYP text between arm and arm64, drop __kvm_hyp_code_start/end, and just use the __hyp_text_start/end symbols. Acked-by: Christoffer Dall <christoffer.dall@linaro.org> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2016-02-29ARM: KVM: Move the HYP code to its own sectionMarc Zyngier
In order to be able to spread the HYP code into multiple compilation units, adopt a layout similar to that of arm64: - the HYP text is emited in its own section (.hyp.text) - two linker generated symbols are use to identify the boundaries of that section No functionnal change.
