Subject: [PATCH 11/26] KVM: x86: Make kvm_mpx_supported() an inline function
Date: Wed, 29 Jan 2020 15:46:25 -0800	[thread overview]
Message-ID: <20200129234640.8147-12-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20200129234640.8147-1-sean.j.christopherson@intel.com>

Expose kvm_mpx_supported() as a static inline so that it can be inlined
in kvm_intel.ko.

No functional change intended.
