Subject: [PATCH 10/22] KVM: x86: Unexport kvm_x86_ops
Date: Fri, 28 Jan 2022 00:51:56 +0000	[thread overview]
Message-ID: <20220128005208.4008533-11-seanjc@google.com> (raw)
In-Reply-To: <20220128005208.4008533-1-seanjc@google.com>

Drop the export of kvm_x86_ops now it is no longer referenced by SVM or
VMX.  Disallowing access to kvm_x86_ops is very desirable as it prevents
vendor code from incorrectly modifying hooks after they have been set by
kvm_arch_hardware_setup(), and more importantly after each function's
associated static_call key has been updated.

No functional change intended.
