[PATCH 10/15] bugs/s390: Pass in 'cond_str' to __EMIT_BUG()

[Ingo Molnar <mingo@kernel.org>]

Pass in the condition string from __WARN_FLAGS(), but do not
concatenate it with __FILE__, because the __bug_table is
apparently indexed by 16 bits and increasing string size
overflows it on defconfig builds.
