From 53b08c347f54970cf5f6ce35b8e1a1fe5f8a11f9 Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Mon, 10 Dec 2018 14:11:35 +0530 Subject: cpuid: Add helper function for cpuid(1) functions This patch introduces 3 helper function for cpuid(1) : 1. cpu_get_cpuid() -> to get processor id (from cpuid.eax) 2. cpu_get_feature_flags_ecx -> to get processor feature flag (from cpuid.ecx) 3. cpu_get_feature_flags_edx -> to get processor feature flag (from cpuid.edx) Above 3 helper functions are targeted to replace majority of cpuid(1) references.
