[-- Type: text/plain, Size: 788 bytes --]
From: Steven Rostedt <rostedt@goodmis.org>
Impact: fix in compiling
GCC can decide to use %dil when "r" is used, which is not valid for
setnz.
This bug was brought out by Stephen Rothwell's merging of the
branch tracer into linux-next.
[ Thanks to Uros Bizjak for recommending 'q' over 'Q' ]
