Ideally bug.h should be including linux/kernel.h itself due to its
TAINT_WARN dependence, it just seems to be getting lucky on other
platforms who either don't have this combination or pull in kernel.h from
somewhere else.

That commit also introduces a linux/bug.h include for WARN_ON() in
linux/thread_info.h which would be similarly insufficient for any
TIF_RESTORE_SIGMASK && !HAVE_SET_RESTORE_SIGMASK platform that also uses
asm-generic/bug.h. 

Given that, I'd prefer stuffing the include in asm-generic directly:

---

bug.h: need linux/kernel.h for TAINT_WARN.

asm-generic/bug.h uses taint flags that are only defined in
linux/kernel.h, resulting in build failures on platforms that
don't include linux/kernel.h some other way:

	arch/sh/include/asm/thread_info.h:172:2: error: 'TAINT_WARN' undeclared (first use in this function)

Caused by commit edd63a2763bd ("set_restore_sigmask() is never called
without SIGPENDING (and never should be)").
