In the context of the currently ongoing work to remove the host kernel
from the TCB under KVM/arm64, I have been trying to wrap the host kernel
with a stage 2 page-table -- see [1].

Using this infrastructure, I attempted to unmap the .hyp. sections from
the host stage 2 as it really shouldn't need to access them. But by
doing so, I realized quickly the module loader was getting very confused
by the usage of EXPORT_SYMBOL() macros in library functions that have
been pulled into the EL2 object, and that we end up linking modules
against the EL2 copy of e.g. memset. And so, this series essentially
tries to fix this.

Applied to kvm-arm64/misc-5.12, thanks!
