Fix uninitialized div_s64 for gcc 4.9

I know we aren't even close to using gcc 4.9, so this might not get merged
for a while, but here it is for when the time comes. :)  4.9 is even more finicky.

Missing include.

lowmemorykiller: Account for highmem during kswapd reclaim

Currenlty most memory reclaim is done through kswapd.
Since kswapd uses a gfp mask of GFP_KERNEL, and because
the lowmemorykiller is zone aware, the lowmemorykiller will
ignore highmem most of the time.
This results in the lowmemorykiller being overly aggressive.

The fix to this issue is to allow the lowmemorykiller to
count highmem when being called by the kswapd if the lowmem
watermarks are satisfied.
