Subject: [PATCH v2 1/3] x86/cpu: Introduce INTEL_CPU_FAM*_NODATA() helper macros
Date: Wed,  9 Jan 2019 18:57:52 +0200	[thread overview]
Message-ID: <20190109165754.90072-1-andriy.shevchenko@linux.intel.com> (raw)

These macros are often used by the drivers and we have already a lot of
duplication as ICPU() macro across them.

Provide a generic x86 macro for users.

This adds no driver data variants.
