Really... *exactly* the same erratum? That sounds pretty unlikely, so I'd
really like to be sure that the workaround we have indeed solves your
problem (issuing a dummy TLBI to 0x0 + dsb, then followed by a dmb + clrex
on each core). The point is that the workaround doesn't simply perform
non-shareable invalidation on each core using IPIs.
/me counts the days until we need this code in arch/arm64.
