OK, bisect result and a caveat:
d88c8958dc13b4e4eb7fc57e3f06dc1c4abc7b1f is the first bad commit

Now, what I tried to do during the bisect was the following:
$ cp /boot/config-3.19.0-14-generic .config
$ make oldconfig
$ make clean
$ make -j `getconf _NPROCESSORS_ONLN` deb-pkg LOCALVERSION=-dpeets??
for ?? an increasing integer, and accepting all default settings for make
oldconfig
HOWEVER, for a vast expanse in the middle of this bisect range, building the
kernel image failed if started from the 3.19 config file (here's one example):
...
INSTALL debian/tmp/lib/firmware/cpia2/stv0672_vp4.bin
INSTALL debian/tmp/lib/firmware/yam/1200.bin
INSTALL debian/tmp/lib/firmware/yam/9600.bin
DEPMOD 3.16.0-dpeets22
depmod: ERROR: Found 5 modules in dependency cycles!
depmod: ERROR: Cycle detected: st21nfcb -> ndlc -> nci -> st21nfcb
depmod: ERROR: Cycle detected: nci -> nci

make[1]: *** [deb-pkg] Error 2
Makefile:1205: recipe for target 'deb-pkg' failed
make: *** [deb-pkg] Error 2
I'm not in a position to do anything other than accept the defaults, and
I'm not about to edit the config file on my own. So for perhaps half of
the bisect steps, the starting point for .config was the previous bisect
step's .config (without first checking whether a copied 3.19 version
worked), or in a couple cases a config file from a known good 3.16
kernel after the 3.19 config file failed. This means that the starting
point was not necessarily the same for all steps.
If there are parts of this I should redo or check, config files you'd
like (I didn't save them in general, but I have a few), or anything I
can test, let me know.
