Subject: [PATCH 4.20 60/76] x86/CPU/AMD: Set the CPB bit unconditionally on F17h
Date: Fri, 8 Mar 2019 13:50:12 +0100 [thread overview]
Message-ID: <20190308124916.922138845@linuxfoundation.org> (raw)
In-Reply-To: <20190308124914.789210760@linuxfoundation.org>
4.20-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jiaxun Yang <jiaxun.yang@flygoat.com>
commit 0237199186e7a4aa5310741f0a6498a20c820fd7 upstream.
Some F17h models do not have CPB set in CPUID even though the CPU
supports it. Set the feature bit unconditionally on all F17h.
