Jan 10 19:41:42 laptop kernel: Fixing recursive fault but reboot is needed!
I won't get time tonight, but I can bisect it tomorrow, so this is just a heads up in case the problem (and fix) jumps
out at anyone. Before I bisect I'll build and run a kernel without the iwlwifi patches.
I've attached the full kernel log file for that boot.

Hi,
I've done the bisect and the outcome is below, but, because I almost always forget to mention it, I'll say here that I
am running a 32 bit user space on a 64 bit kernel.

The bisect ended up at:
7a3ef208e662f4b63d43a23f61a64a129c525bbc is the first bad commit
commit 7a3ef208e662f4b63d43a23f61a64a129c525bbc
Author: Konstantin Khlebnikov <koct9i@gmail.com>
Date: Thu Jan 8 14:32:15 2015 -0800
mm: prevent endless growth of anon_vma hierarchy
Constantly forking task causes unlimited grow of anon_vma chain. Each
next child allocates new level of anon_vmas and links vma to all
previous levels because pages might be inherited from any level.
This patch adds heuristic which decides to reuse existing anon_vma
instead of forking new one. It adds counter anon_vma->degree which
counts linked vmas and directly descending anon_vmas and reuses anon_vma
if counter is lower than two. As a result each anon_vma has either vma
or at least two descending anon_vmas. In such trees half of nodes are
leafs with alive vmas, thus count of anon_vmas is no more than two times
bigger than count of vmas.
This heuristic reuses anon_vmas as few as possible because each reuse
adds false aliasing among vmas and rmap walker ought to scan more ptes
when it searches where page is might be mapped.

Looks like degree (%edx) is 1 on anon-vma desruction.
Probably I've overlooked some weird conrner case in vma splitting/merging.
Could you try this patch. It disables vma merging end eliminates half
of complicated paths.
As I see merging is optional, everything should work fine without it.

Thanks for the fast reply.
I applied the patch and tested it. I wasn't able to reproduce *my* problem,
so you are definitely in the right direction :)

[-- Attachment #2: mm-fix-anon_vma-degree-counter-in-case-of-anon_vma-export --]

mm: fix anon_vma degree counter in case of anon_vma export
From: Konstantin Khlebnikov <koct9i@gmail.com>
anon_vma_clone() is usually called for copy of source vma in dst argument.
If source vma has anon_vma it should be already in dst->anon_vma.
NULL pointer in dst->anon_vma means clone is called from anon_vma_fork and
anon_vma_clone() should try to reuse some old anon_vma.
vma_adjust() calls it differently and breaks anon_vma degree counter logic.
This patch copies anon_vma pointer to satisfy anon_vma_clone() expectations.
