title: Linux kernel git tree - version.h is not refreshed
body: <p>I'm compiling a kernel module and realized the include/linux/version.h is not refresh despite I checkout the new kernel from git and ran make modules_prepare. I also tried to remove include/linux/version.h, but it's not regenerate when I run make modules_prepare.</p>
  
  <p>Any idea how can I get an up to date version.h?</p>
