[PATCH kernel-4.19 2/6] x86/cpu: Remove redundant cpu_detect_cache_sizes() call
by LeoLiu-oc 25 Mar '21

25 Mar '21

mainline inclusion from mainline-5.6 commit 283bab9809786cf41798512f5c1e97f4b679ba96 category: x86/cpu -------------------------------- Both functions call init_intel_cacheinfo() which computes L2 and L3 cache sizes from CPUID(4). But then they also call cpu_detect_cache_sizes() a bit later which computes ->x86_tlbsize and L2 size from CPUID(80000006). However, the latter call is not needed because - on these CPUs, CPUID(80000006).EBX for ->x86_tlbsize is reserved - CPUID(80000006).ECX for the L2 size has the same result as CPUID(4) Therefore, remove the latter call to simplify the code.
