From: Drew Davenport <ddavenport@xxxxxxxxxxxx>
Subject: include/asm-generic/bug.h: fix "cut here" for WARN_ON for __WARN_TAINT architectures
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.
