Will Deacon 15a511c0cb arm64: erratum: Work around Falkor erratum #E1003 in trampoline code ... Commit d1777e686a upstream. We rely on an atomic swizzling of TTBR1 when transitioning from the entry trampoline to the kernel proper on an exception. We can't rely on this atomicity in the face of Falkor erratum #E1003, so on affected cores we can issue a TLB invalidation to invalidate the walk cache prior to jumping into the kernel. There is still the possibility of a TLB conflict here due to conflicting walk cache entries prior to the invalidation, but this doesn't appear to be the case on these CPUs in practice.
