└─>Cortex-A57: 832075: possible deadlock on mixing exclusive memory accesses with device loads
In linux kernel since version 3.18.2 (release Date: 2015-01-08)
This option adds an alternative code sequence to work around ARM
erratum 832075 on Cortex-A57 parts up to r1p2.
Affected Cortex-A57 parts might deadlock when exclusive load/store
instructions to Write-Back memory are mixed with Device loads.
The workaround is to promote device loads to use Load-Acquire
semantics.
Please note that this does not necessarily enable the workaround,
as it depends on the alternative framework, which will only patch
the kernel if an affected CPU is detected.
If unsure, say Y.
