[PATCH 2/2] KVM: arm64: Stub EXPORT_SYMBOL for nVHE EL2 code

[Quentin Perret]

In order to ensure the module loader does not get confused if a symbol
is exported in EL2 nVHE code (as will be the case when we will compile
e.g. lib/memset.S into the EL2 object), make sure to stub all exports
using __DISABLE_EXPORTS in the nvhe folder.
