From aba5b397cad7d398b385aaf5029f99f41b690466 Mon Sep 17 00:00:00 2001 From: "Borislav Petkov (AMD)" Date: Sun, 18 Dec 2022 13:04:05 +0100 Subject: [PATCH] hamradio: baycom_epp: Do not use x86-specific rdtsc() Use get_cycles() which is provided by pretty much every arch. The UML build works too because get_cycles() is a simple "return 0;" because the rdtsc() is optimized away there. Signed-off-by: Borislav Petkov (AMD) Signed-off-by: David S.
