arm64: KVM: Remove weak attributes

2015-12-14T11:30:44Z

As we've now switched to the new world switch implementation, remove the weak attributes, as nobody is supposed to override it anymore. Acked-by: Christoffer Dall Signed-off-by: Marc Zyngier

arm64: KVM: Turn system register numbers to an enum

2015-12-14T11:30:43Z

Having the system register numbers as #defines has been a pain since day one, as the ordering is pretty fragile, and moving things around leads to renumbering and epic conflict resolutions. Now that we're mostly acessing the sysreg file in C, an enum is a much better type to use, and we can clean things up a bit. Signed-off-by: Marc Zyngier Acked-by: Christoffer Dall

arm64: KVM: Add compatibility aliases

2015-12-14T11:30:42Z

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.
