[RFC PATCH v2 09/26] KVM: arm64: Allow using kvm_nvhe_sym() in hyp code

From: Quentin Perret
Date: Fri Jan 08 2021 - 07:18:39 EST


In order to allow the usage of code shared by the host and the hyp in
static inline library function, allow the usage of kvm_nvhe_sym() at el2
by defaulting to the raw symbol name.
