In # flush_coherent_icache() we implement an optimisation for CPUs where we # know we don't actually have to flush the whole range, we just need to # do a single icbi. # # However we still execute the icbi on the user address of the start of # the range we're flushing. On CPUs that also implement KUAP (Power9) # that leads to the spurious fault above. # # We should be able to pass any address, including a kernel address, to # the icbi on these CPUs, which would avoid any interaction with KUAP. # But I don't want to make that change in a bug fix, just in case it # surfaces some strange behaviour on some CPU. # # So for now just disable KUAP around the icbi. Note the icbi is treated # as a load, so we allow read access, not write as you'd expect. # # Fixes: 890274c2dc4c ("powerpc/64s: Implement KUAP for Radix MMU") # Cc: stable@vger.kernel.org # v5.2+ #
