Hi, Will,

I'll merge the arm64 diff I proposed. Could you repost the ARM part please?

I've just reposted it, hopefully we can get that merged in soon as well.

I think enabling and activating kgdb by default is a pretty crazy thing to
do, but I agree that we shouldn't allow userspace to trap into it either.

Agreed, hopefully the actual footprint of this bug isn't too large, but it's
worth fixing anyways.

Once you repost the ARM patches, we can look at getting them merged via rmk.

Cheers,

Will

Thanks again!
