Subject: powerpc: Convert cpu_to_l2cache() to of_find_next_cache_node()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b2ea25b958968c152c6fac0594f2c9aa8b59eb8d;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

powerpc: Convert cpu_to_l2cache() to of_find_next_cache_node()

The smp code uses cache information to populate cpu_core_map; change
it to use common code for cache lookup.
