From 9b692102d87d13d24c97461207cae259121ed44b Mon Sep 17 00:00:00 2001 From: Vasily Gorbik Date: Mon, 19 Aug 2019 23:14:10 +0200 Subject: s390/mem_detect: provide single get_mem_detect_end get_mem_detect_end is already used in couple of places with potential to be utilized in more cases. Provide single get_mem_detect_end implementation in asm/mem_detect.h to be used by kasan and startup code.
