Hi Paolo,
Please do a pull from my paulus/powerpc tree to get a fix for a bug
that can cause the host to crash when a guest resizes its hashed page
table. I would like this to go into 4.14 if that is still possible.
I have done a signed tag this time. It is signed with a new signing
sub-key (2C63719F) that I made today, so you will need to fetch it if
you want to check the signature. It is a sub-key on my key EC9DBB8C
which had expired, but I have set the expiry to "never" now, so you
will need to re-fetch that one too.
I am going to do an equivalent fix on my kvm-ppc-next branch also, but
it will look different because the fix touches the same code that my
recent HPT-on-radix patch series touches.
Thanks,
Paul.
