My patch doesn't address your issue, it only addresses a previous
problem. We're still decrementing the stack pointer and writing to
a possible new page - which could fault.
Therefore, your patch is still required, but it needs to be modified
to apply on top of my patch.
A replacement patch would be welcome.
