Hi, I hit the following when resetting my ADSL modem, which dropped the
Ethernet link on this pc using the current Linus' git head kernel
compiled for X86-64 in 32 bit mode:

This and other mmamp related problems appear to have surfaced in the
Linus' git head kernel in the last few days.
I'm happy to supply further information or run tests to help identify
the source of the problem.

More likely this is already fixed in v3.19-rc4 by:
b800c91a0517071156e772d4fb329ad33590da62
(mm: fix corner case in anon_vma endless growing prevention)
and there is one fix for rare error on error path in linux-mm:
(mm: fix anon_vma->degree underflow in anon_vma endless growing prevention)
