Subject: [PATCH v4 09/34] KVM: arm64: Allow using kvm_nvhe_sym() in hyp code
Date: Wed, 10 Mar 2021 17:57:26 +0000	[thread overview]
Message-ID: <20210310175751.3320106-10-qperret@google.com> (raw)
In-Reply-To: <20210310175751.3320106-1-qperret@google.com>

In order to allow the usage of code shared by the host and the hyp in
static inline library functions, allow the usage of kvm_nvhe_sym() at
EL2 by defaulting to the raw symbol name.

Acked-by: Will Deacon <will@kernel.org>
