Subject: [PATCH 4.14 19/31] ARM: fix co-processor register typo
Date: Thu, 10 Mar 2022 15:18:32 +0100 [thread overview]
Message-ID: <20220310140808.096982909@linuxfoundation.org> (raw)
In-Reply-To: <20220310140807.524313448@linuxfoundation.org>
From: Russell King (Oracle) <rmk+kernel@armlinux.org.uk>

In the recent Spectre BHB patches, there was a typo that is only
exposed in certain configurations: mcr p15,0,XX,c7,r5,4 should have
been mcr p15,0,XX,c7,c5,4
Reported-by: kernel test robot <lkp@intel.com>
