Kent, Jens, Christoph et al,
please see this bugzilla:

where Artem Tashkinov bisected his problems with 4.3 down to commit
b54ffb73cadc ("block: remove bio_get_nr_vecs()") that you've all
signed off on.
Artem,
can you re-check the commits around this series again? I would be
extremtly surprised if it's really this particular commit and not
one just before it causing the problem - it just allocates bios
to the biggest possible instead of only allocating up to what
bio_add_page would accept.
I'm positive about this particular commit. Of course, it might be
another
GCC 4.7.4 miscompilation which causes the errors which shouldn't be
there but
I'm not an expert, so.
