Marc Zyngier 13720a56ed arm64: KVM: Move kvm/hyp/hyp.h to include/asm/kvm_hyp.h
In order to be able to move code outside of kvm/hyp, we need to make
the global hyp.h file accessible from a standard location.

include/asm/kvm_hyp.h seems good enough.

Marc Zyngier 3ffa75cd18 arm64: KVM: Remove weak attributes
As we've now switched to the new world switch implementation,
remove the weak attributes, as nobody is supposed to override
it anymore.

Marc Zyngier 044ac37d12 arm64: KVM: Add compatibility aliases
So far, we've implemented the new world switch with a completely
different namespace, so that we could have both implementation
compiled in.

Let's take things one step further by adding weak aliases that
have the same names as the original implementation. The weak
attributes allows the new implementation to be overriden by the
old one, and everything still work.

At a later point, we'll be able to simply drop the old code, and
everything will hopefully keep working, thanks to the aliases we
have just added. This also saves us repainting all the callers.
