Subject[PATCH] lib: Taint kernel in common report_bug() WARN path.
Commit 95b570c9cef3b12356454c7112571b7e406b4b51 introduced a
TAINT_WARN that was implemented for all architectures using the
generic warn_on_slowpath(), which excluded any architecture that
set HAVE_ARCH_WARN_ON.

As all of the architectures that implement their own WARN_ON()
all go through the report_bug() path (specifically handling
BUG_TRAP_TYPE_WARN), taint the kernel there as well for consistency.

Tested on avr32 and sh. Also relevant for s390, parisc, and powerpc.
