I assume you target 5.5 with this workaround. I don't mind merging it but if you want to queue it, we already have a stable for-next/neoverse-n1-stale-instr branch with 1542419 (I'll push a fixup on top soon for a clang warning). The other issue is that we get a conflict with mainline due to the tx2 erratum. If it gets too complicated, I'll also merge for-next/fixes into for-next/core. -- Catalin _______________________________________________ kvmarm mailing list kvmarm@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
