Subject: misleading kernel config error msg when building module against
 kernel


  when one tries to build a simple module against a "make distclean"ed
source tree, one gets:

 ERROR: Kernel configuration is invalid.
         include/generated/autoconf.h or include/config/auto.conf are missing.
         Run 'make oldconfig && make prepare' on kernel src to fix it.

that diagnostic seems inaccurate in two ways.

  first, "make oldconfig" is unnecessarily specific -- it should
really just say, "you must configure your kernel source first."

  and second, "make prepare" should really say "make modules_prepare",
should it not?

  anyone mind if i submit a patch?
