I don't feel brave enough to take a series affecting all architectures so late in the game, and the whole thing had very little arm64 exposure. The latest QEMU doesn't seem to work anymore, so I don't have any MTE-capable emulation (and using the FVP remotely is a pain in the proverbial neck). I'll come back to this after the merge window, should Peter decide to respin the series. Thanks, M. -- Without deviation from the norm, progress is not possible. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
