Hi Willem,

https://github.com/0day-ci/linux/commits/Willem-de-Bruijn/sock-allocate-skbs-from-optmem/20170619-072924
config: i386-randconfig-a0-06162344 (attached as .config)
compiler: gcc-5 (Debian 5.4.1-2) 5.4.1 20160904
reproduce:
# sa
From: Willem de Bruijn
Refine skb_copy_ubufs to support compound pages. With upcoming TCP
and UDP zerocopy sendmsg, such fragments may appear.
The existing code replaces each page one for one. Splitting each
compound page into an independent number of regular pages can result
in exceeding limit
