Nicholas Piggin	28f07fab26	powerpc/vdso: Fix __kernel_sync_dicache sequence with coherent icache ... Processors with coherent icache require the sequence sync ; icbi ; isync to entire store->execute coherency. icbi (to any address) must be executed to ensure isync flushes the pipeline. See "POWER9 Processor User's Manual, 4.6.2.2 Instruction Cache Block Invalidate (icbi)" for details. __kernel_sync_dicache is missing icbi for the coherent icache path. Add it.
