Fix compile breakage with kref.h

[James Bottomley]

This set of build failures just started appearing on parisc:

In file included from drivers/input/serio/serio_raw.c:12:
include/linux/kref.h: In function 'kref_get':
include/linux/kref.h:40: error: 'TAINT_WARN' undeclared (first use in this function)
include/linux/kref.h:40: error: (Each undeclared identifier is reported only once
include/linux/kref.h:40: error: for each function it appears in.)
include/linux/kref.h: In function 'kref_sub':
include/linux/kref.h:65: error: 'TAINT_WARN' undeclared (first use in this function)

It happens because TAINT_WARN is defined in kernel.h and this particular
compile doesn't seem to include it (no idea why it's just
manifesting ... probably some #include file untangling exposed it).  Fix
by adding #include <linux/kernel.h> to linux/kref.h

Does adding <linux/bug.h> fix it instead?  We are using WARN_ON() here.
Hm, but that needs kernel.h as well, ugh, what a mess.

I've got some work done already towards cleaning this up; aiming for
getting it done and in linux-next for the 3.4 cycle.
