Subject: [PATCH v5 5/9] x86/cpu: Name CPU matching macro more generically (and shorten)
Date: Wed, 11 Dec 2024 22:57:47 -0800	[thread overview]
Message-ID: <20241211-add-cpu-type-v5-5-2ae010f50370@linux.intel.com> (raw)
In-Reply-To: <20241211-add-cpu-type-v5-0-2ae010f50370@linux.intel.com>

To add cpu-type to the existing CPU matching infrastructure, the base macro
X86_MATCH_VENDOR_FAM_MODEL_STEPPINGS_FEATURE need to append _CPU_TYPE. This
makes an already long name longer, and somewhat incomprehensible.

To avoid this, rename the base macro to X86_MATCH_CPU. The macro name
doesn't need to explicitly tell everything that it matches. The arguments
to the macro already hints that.

For consistency, use this base macro to define X86_MATCH_VFM and friends.
