Subject: [PATCH v3 0/3] Cortex-A77 erratum 1508412 workaround
Date: Fri, 17 Jul 2020 14:52:30 -0600 [thread overview]
Message-ID: <20200717205233.903344-1-robh@kernel.org> (raw)
This series implements the work-around for Cortex-A77 erratum 1508412.
KVM guests which don't implement the workaround can still deadlock the
system. This is also the case with the existing Cortex-A57 erratum 832075,
so we add a warning message if an erratum can cause deadlock.
Changes detailed in patches.
