The mistake is harmless here: Since the default symbol is not visible, the choice falls back on using the visible symbol as the default instead, which is CC_OPTIMIZE_FOR_PERFORMANCE, as intended. A patch that makes Kconfig print a warning in this case has been submitted separately: http://www.spinics.net/lists/linux-kbuild/msg15566.html Link: http://lkml.kernel.org/r/1507074806-21577-1-git-send-email-ulfalizer@gmail.com Signed-off-by: Ulf Magnusson Acked-by: Arnd Bergmann Cc: Paul E .
