+ help
+ On Cavium ThunderX2, a load, store or prefetch instruction between a
+ TTBR update and the corresponding context synchronizing operation can
+ cause a spurious Data Abort to be delivered to any hardware thread in
+ the CPU core.
+
+ Work around the issue by avoiding the problematic code sequence and
+ trapping KVM guest TTBRx_EL1 writes to EL2 when SMT is enabled. The
+ trap handler performs the corresponding register access, skips the
+ instruction and ensures context synchronization by virtue of the
+ exception return.
