ARM: KVM: Add TLB invalidation code Convert the TLB invalidation code to C, hooking it into the build system whilst we're at it. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>

ARM: KVM: Add CP15 save/restore code Concert the CP15 save/restore code to C. Reviewed-by: Christoffer Dall <christoffer.dall@linaro.org> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>

ARM: KVM: Add timer save/restore 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.

ARM: KVM: Add VFP save/restore This is almost a copy/paste of the existing version, with a couple of subtle differences: - Only write to FPEXC once on the save path - Add an isb when enabling VFP access The patch also defines a few sysreg accessors and a __vfp_enabled predicate that test the VFP trapping state.

ARM: KVM: Add banked registers save/restore Banked registers are one of the many perks of the 32bit architecture, and the world switch needs to cope with it. This requires some "special" accessors, as these are not accessed using a standard coprocessor instruction.

ARM: KVM: Add guest entry code Add the very minimal piece of code that is now required to jump into the guest (and return from it). This code is only concerned with save/restoring the USR registers (r0-r12+lr for the guest, r4-r12+lr for the host), as everything else is dealt with in C (VFP is another matter though).

ARM: KVM: Add the new world switch implementation The new world switch implementation is modeled after the arm64 one, calling the various save/restore functions in turn, and having as little state as possible.
