Thanks for adding me to CC.

Werner, could you send me the vmlinux (or bzImage) of the exact kernel
that crashed (don't rebuild), otherwise I don't know where it
crashed...

Crash on booting sounds like it's very reproducible, that's great so
we fix it immediately (maybe it's related to highpte or some other
.config difference that wasn't exercised). Probably 32bit THP got 0.1%
of the testing that 64bit version had... (if I don't get a
vmlinux/bzImage of the kernel that crashed soon, I'll try to reproduce
on a VM with the .config attached, I've no host with 32bit userland
anymore..).
