From e05efd31b9db39ccd9c489c0f93df7a8e8cb48a8 Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Sat, 23 Apr 2022 21:11:41 +0200 Subject: [PATCH] s390: define get_cycles macro for arch-override commit 2e3df523256cb9836de8441e9c791a796759bb3c upstream. S390x defines a get_cycles() function, but it does not do the usual `#define get_cycles get_cycles` dance, making it impossible for generic code to see if an arch-specific function was defined. While the get_cycles() ifdef is not currently used, the following timekeeping patch in this series will depend on the macro existing (or not existing) when defining random_get_entropy().
