This small series reworks various bits of the host EL2 entry after Andrew's extensive rework to move from direct function calls to a SMCCC implementation. The first 3 patches are plain bug fixes, and candidates for immediate merge into 5.10. The following 2 patches allow the use of direct function pointers at EL2, something that we can't do at the moment (other than PC-relative addressing). This requires a helper to translate pointers at runtime, but the result is neat enough. This allows the rewrite of the host HVC handling in a more maintainable way. A similar patch removes the direct use of kimage_voffset, which we won't be able to trust for much longer. The last two patches are just cleanups and optimisations. Patches on top of 5.10-rc1.
