From cad5b35da9f7e429131592421c463a93703bb02e Mon Sep 17 00:00:00 2001 From: Vasily Gorbik Date: Tue, 12 Jun 2018 22:58:50 +0200 Subject: s390/decompressor: reuse lib/mem.S for mem functions Reusing arch/s390/lib/mem.S file solves a problem that sclp_early_core.c and its dependencies have to be compiled with -march=z900 (no need to compile compressed/misc.c with -march=z900). This also allows to avoid mem functions duplicates, makes code a bit smaller and optimized mem functions are utilized.
