Hi Dave,

Thank you for your reply.

Your fix looks correct and seems to work.  For stylistic reasons, I may
write it like this instead, but the effect should be the same:

	header->max_vl = sve_max_vl;
	if (WARN_ON(!sve_vl_valid(sve_max_vl))
		header->max_vl = header->vl;

It is better than my fix.
Please, apply it at next version.

I've rebased to v4.13 and pushed a branch to track fixes against v2,
here:

 * http://linux-arm.org/git?p=linux-dm.git;a=shortlog;h=refs/heads/sve/v2%2Bfixes

 * git://linux-arm.org/linux-dm.git sve/v2+fixes

Cheers
---Dave
