linux-next: build failure after merge of the printk tree

[Stephen Rothwell]

Hi Petr,

After merging the printk tree, today's linux-next build (x86_64
allnoconfig) failed like this:

lib/vsprintf.o: In function `pointer':
vsprintf.c:(.text+0x2260): undefined reference to `dereference_symbol_descriptor'

Caused by commit

  b77929215209 ("symbol lookup: introduce dereference_symbol_descriptor()")

I have reverted that commit for today.
