Subject: [PATCH] bug: Fix "cut here" for WARN_ON for __WARN_TAINT architectures
Date: Mon, 24 Jun 2019 09:48:31 -0600
Message-ID: <> (raw)

For architectures using __WARN_TAINT, the WARN_ON macro did not
print out the "cut here" string. The other WARN_XXX macros would
print "cut here" inside __warn_printk, which is not called for
WARN_ON since it doesn't have a message to print.

Fixes: a7bed27af194 ("bug: fix "cut here" location for __WARN_TAINT architectures")
