[Bug 965125] kernel crashes with divide error: 0000 in e1000e driver

--- Comment #4 from Takashi Iwai <tiwai@xxxxxxxx> ---
I prepared a quickfix KMP containing a few patches for the relevant code from
the upstream and a debug patch, found at OBS home:tiwai:bnc965125 repo.

The backported patches are:
e1000e: fix systim issues
e1000e: Fix tight loop implementation of systime read algorithm
e1000e: fix division by zero on jumbo MTUs

(The last one is about the different code path, but it also gives the same
"divide error", so just to be sure.)

With the additional debug patch, incvalue=0 will give just a warning but no
crash. Let's see whether we still get this warning, or it's covered by some
patch above.
