Jan's fix appears to have solved 1) above, but 2) posix/mprotect is
still failing.  Thanks for the xeno-regression-test tips; ran a couple
more (not for a long time, will do that later).

Test runs:

Kernel config (only change is disabling TRANSPARENT_HUGEPAGE):

Dmesg output with no oops (hopefully boring):
