Hi,

my crisv32 qemu test fails with next-20150917 as follows.

NET: Registered protocol family 16
kernel BUG at mm/slab.c:1648!
Linux 4.3.0-rc1-next-20150917 #1 Wed Sep 16 23:56:59 PDT 2015
Oops: 0000

[ register dump follows ]

See http://server.roeck-us.net:8010/builders/qemu-crisv32-next/builds/83/steps/qemubuildcommand/logs/stdio
for a complete log.

Bisect points to 'page-flags: define behavior SL*B-related flags on compound pages'.

One of the bisect steps, at 'mm: support madvise(MADV_FREE)', causes a build failure,
but that did not seem to affect the overall bisect results. Just for completeness,
here is the reported build failure.

mm/vmscan.c: In function ‘shrink_page_list’:
mm/vmscan.c:1093:5: error: implicit declaration of function ‘__clear_page_locked’ [-Werror=implicit-function-declaration]
      __clear_page_locked(page);
      ^
