Andrew Pinski	104a0c02e8	arm64: Add workaround for Cavium erratum 27456 ... On ThunderX T88 pass 1.x through 2.1 parts, broadcast TLBI instructions may cause the icache to become corrupted if it contains data for a non-current ASID. This patch implements the workaround (which invalidates the local icache when switching the mm) by using code patching.

Will Deacon	9cb9c9e5ba	arm64: Documentation: add list of software workarounds for errata ... It's not immediately obvious which hardware errata are worked around in the Linux kernel for an arbitrary kernel tree, so add a file to keep track of what we're working around.
