Subject: [PATCH 05/10] KVM: x86: Rename get_msr_feature() APIs to get_feature_msr()
From: Sean Christopherson <seanjc@google.com>
To: Sean Christopherson <seanjc@google.com>, Paolo Bonzini <pbonzini@redhat.com>
Cc: kvm@vger.kernel.org, linux-kernel@vger.kernel.org, 
	Tom Lendacky <thomas.lendacky@amd.com>, Weijiang Yang <weijiang.yang@intel.com>
Content-Type: text/plain; charset="UTF-8"

Rename all APIs related to feature MSRs from get_feature_msr() to
get_feature_msr().  The APIs get "feature MSRs", not "MSR features".
And unlike kvm_{g,s}et_msr_common(), the "feature" adjective doesn't
describe the helper itself.

No functional change intended.
