From 0784a64659c6e30efa6297c620492d1580039683 Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Tue, 30 Aug 2022 18:27:34 +0800 Subject: [PATCH] parisc: define get_cycles macro for arch-override stable inclusion from stable-v5.10.119 commit c55a863c304e7301237c6c057350cf01d4ca9716 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5L6BB Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=c55a863c304e7301237c6c057350cf01d4ca9716 -------------------------------- commit 8865bbe6ba1120e67f72201b7003a16202cd42be upstream. PA-RISC 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().
