Subject: [PATCH 14/16] x86/cpufeatures: Clean up synthetic virtualization flags
Date: Fri, 4 Oct 2019 14:56:13 -0700 [thread overview]
Message-ID: <20191004215615.5479-15-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20191004215615.5479-1-sean.j.christopherson@intel.com>
Shift the remaining synthetic virtualization flags so that the flags
are contiguous starting from bit 0.
No functional change intended.
