SubjectRe: Kernel falls apart under light memory pressure (i.e. linking vmlinux)

Here are some logs for two different failure mores.

incorrect_oom_kill.txt is an OOM kill when there was lots of available
swap to use. AFAICT the kernel should not have OOM killed at all.

stuck_xyz is when the system is wedged with plenty (~300MB) free
memory but no swap. The sysrq files are self-explanatory.
stuck-sysrq-f.txt is after the others so that it won't have corrupted
the output. After taking all that data, I waited awhile and started
getting soft lockup messges.

I'm having trouble reproducing the "stuck" failure mode on my
lockdep-enabled kernel right now (the OOM kill is easy), so no lock
state trace. But I got one yesterday and IIRC it showed a few tty
locks and either kworker or kcryptd holding (kqueue) and
((&io->work)).

I compressed the larger files.
