From bd067f83b0840e798328d14133ce4542d3bf9e71 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Sun, 8 Jan 2017 17:31:45 -0600 Subject: powerpc/64: Fix naming of cache block vs. cache line In a number of places we called "cache line size" what is actually the cache block size, which in the powerpc architecture, means the effective size to use with cache management instructions (it can be different from the actual cache line size). We fix the naming across the board and properly retrieve both pieces of information when available in the device-tree.
