X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2045124ffd1a5e46d157349016a2c50f19c8c91d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ARM: 5888/1: arm: Update comments in cacheflush.h and remove unnecessary V6 and V7 comments The comments in cacheflush.h should follow what's in struct cpu_cache_fns. The comments for V6 and V7 are unnecessary.
