Subject: [PATCH 1/1] x86/cpu/intel: enable X86_FEATURE_NONSTOP_TSC_S3 for Merrifield
Date: Thu, 8 Oct 2015 18:56:26 +0300 [thread overview]
Message-ID: <1444319786-36125-1-git-send-email-andriy.shevchenko@linux.intel.com> (raw)
The Intel Merrifield SoC is a successor of the Intel MID line of SoCs. Let's
set the neccessary capability for that chip. See commit c54fdbb2823d (x86: Add
cpu capability flag X86_FEATURE_NONSTOP_TSC_S3) for the details.
