So far, we're using a complicated sequence of alternatives to patch the kernel/hyp VA mask on non-VHE, and NOP out the masking altogether when on VHE. The newly introduced dynamic patching gives us the opportunity to simplify that code by patching a single instruction with the correct mask (instead of the mind bending cumulative masking we have at the moment) or even a single NOP on VHE. This also adds some initial code that will allow the patching callback to switch to a more complex patching.
