From de39b19452e784de5f90ae899851ab29a29bb42c Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Fri, 14 Aug 2020 05:56:26 +0000 Subject: powerpc: Rewrite 4xx flush_cache_instruction() in C Nothing prevents flush_cache_instruction() from being writen in C. Do it to improve readability and maintainability.
