| |
Hi Greg,
We stumbled over a change in linux-next that has ABI implications for arm64 and, as far as we can tell, has not been reviewed:
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/arch/arm64/kernel?id=fb7ff3f8721b87bf078868c9a252fa0cf71a47c2
("fb7ff3f8721b cpuinfo: implement sysfs nodes for arm64")
It looks like this was requested by you on LKML here:
https://lkml.org/lkml/2017/8/2/663
but these sorts of changes really need to go on the linux-arm-kernel mailing list with the maintainers on cc so that the patches can be properly reviewed and eventually acked if appropriate. In this case, I can't find any trace of the patch on any of the mailing lists to which I'm subscribed.
Please can you drop this from your tree until we've had a chance to review it properly? If Felix can repost it as above, then we can get the discussion started because, aside from this email, we have concerns about exactly what is being exposed to userspace here.
Thanks,
Will
