Rob Herring f5da59f2bb arm64: errata: Add Cortex-A510 speculative unprivileged load workaround ... commit f827bcdafa upstream. Implement the workaround for ARM Cortex-A510 erratum 3117295. On an affected Cortex-A510 core, a speculatively executed unprivileged load might leak data from a privileged load via a cache side channel. The issue only exists for loads within a translation regime with the same translation (e.g. same ASID and VMID). Therefore, the issue only affects the return to EL0. The erratum and workaround are the same as ARM Cortex-A520 erratum 2966298, so reuse the existing workaround.
