Subject: [PATCH v8 43/55] i386/cgs: Rename *mask_cpuid_features() to *adjust_cpuid_features()
Date: Tue,  1 Apr 2025 09:01:53 -0400	[thread overview]
Message-ID: <20250401130205.2198253-44-xiaoyao.li@intel.com> (raw)
In-Reply-To: <20250401130205.2198253-1-xiaoyao.li@intel.com>

Because for TDX case, there are also fixed-1 bits that enfored by TDX
module.
