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.

mm: Increase number of GFP masks

The __GFP_CMA mask is now placed after all available GFP masks.
With this we need to increase the total number of GFP flags.
Do so accordingly.
