x86: Handle _SC_LEVEL1_ICACHE_LINESIZE [BZ #27444]
commit 2d651eb9265d1366d7b9e881bfddd46db9c1ecc4
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Fri Sep 18 07:55:14 2020 -0700
x86: Move x86 processor cache info to cpu_features
missed _SC_LEVEL1_ICACHE_LINESIZE.
1. Add level1_icache_linesize to struct cpu_features.
2. Initialize level1_icache_linesize by calling handle_intel,
handle_zhaoxin and handle_amd with _SC_LEVEL1_ICACHE_LINESIZE.
3. Return level1_icache_linesize for _SC_LEVEL1_ICACHE_LINESIZE.
