From 73267b435c31868c61770a8371765e5e552b5174 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Thu, 4 Oct 2018 19:22:27 +0200 Subject: [PATCH] cpu/SMT: State SMT is disabled even with nosmt and without "=force" [ Upstream commit d0e7d14455d41163126afecd0fcce935463cc512 ] When booting with "nosmt=force" a message is issued into dmesg to confirm that SMT has been force-disabled but such a message is not issued when only "nosmt" is on the kernel command line. Fix that.
