x86: printk kernel version in WARN_ON and other dump_stack users
today, all oopses contain a version number of the kernel, which is nice because the people who actually do bother to read the oops get this vital bit of information always without having to ask the reporter in another round trip. However, WARN_ON() and many other dump_stack() users right now lack this information; the patch below adds this. This information is essential for getting people to use their time effectively when looking at these things; in addition, it's essential for tools that try to collect statistics about defects. Please consider, since its so simple and important for long term kernel quality processes. The code is identical between 32/64 bit; a lot of this code should be unified over time, the patch keeps the identical-ness intact.
