Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/mtd/ubi/io.c: In function 'ubi_dbg_check_write':
drivers/mtd/ubi/io.c:1348: error: 'PAGE_KERNEL' undeclared (first use in this function)
drivers/mtd/ubi/io.c: In function 'ubi_dbg_check_all_ff':
drivers/mtd/ubi/io.c:1412: error: 'PAGE_KERNEL' undeclared (first use in this function)

Caused by commit 823ed5091113 ("UBI: allocate write checking buffer on demand").

I don't know how to fix this, so I have left it for today.

Hmm, strange, include <linux/vmalloc.h> should be enough to use
__vmalloc with 'PAGE_KERNEL' AFAICS, and we have this include... I'll
try to look better.

Try adding asm/pgtable.h 

Cheers,
Ben.
