That rules out any arm32 specific changes - the last time my tree
changed in for-next was 1st April.
Ard points out that the pte table is on the stack, which it really
should not be. I'm guessing there's some inappropriate generic
kernel change that has broken arm32. A pte table should never ever
appear on a kernel stack.
