Hi Andrew,

After merging the akpm-current tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

ERROR: "kmalloc_order" [drivers/net/wireless/brcm80211/brcmfmac/brcmfmac.ko] undefined!

Caused by commit a3ed1ed24850 ("mm: get rid of __GFP_KMEMCG").

I added the following patch:
