This is a merge commit, so the bisection result is not very useful:

   git-log --pretty=oneline 791a9a666d1afe2603bcb2c6a4852d684e879252..edf9364d3f924aff6f77176b8e52a4b68e5c30d6 | wc -l
   2233

The error message is this:

   ERROR: "__udivdi3" [fs/ufs/ufs.ko] undefined!
   scripts/Makefile.modpost:91: recipe for target '__modpost' failed
   make[1]: *** [__modpost] Error 1

I searched the commit log and CC'd a couple of people who have fixed
similar bugs elsewhere.

Ian.

It's 64bit ->s_dsize going through "multiply by this, divide by 100".
Can be papered over by using mul_64_u32_div() in ufs_new_fragments(),
but
	* expression remains unchanged, so it's better done at
mount time
	* there's a braino (since circa 2002) in the same code
- the expression(s) are for the levels of fragmentation that
trigger switches in hysteresis loop and both switches lead to
the same state due to cut'n'paste damage
	* for really low minfree we get those levels too close
to each other - at minfree 5 we get 0.025 .. 0.03, at minfree 4
they outright merge and below that the upper bound is less than
the lower one.  We'd copied the original 4.4BSD here; at 1995
FreeBSD got switched to "minfree 5 or below means using OPTSPACE
all the time".

Fixed in vfs.git#ufs-fixes; see commit 77e9ce327d9b607cd6e57c0f4524a654dc59c4b1
there.  Not sure if it's worth splitting...

I can confirm that commit fixes the build for m68k.
Let's hope it fixes the build for all other 32-bit platforms, too ;-)

If I'm not mistaken, the commit that caused the breakage was never part of
linux-next before it entered mainline?
Can you please make sure all commits cook a few days in linux-next before
they are sent upstream?

Thanks!

Gr{oetje,eeting}s,

It's not an excuse, but I got too used to 0-day buildbot catching that kind
of stuff within a day or so ;-/  Should've done cross-builds myself, of course -
my fault...
