Attached patch adds a range check to LOG_BUF_SHIFT and clarifies the
configuration somewhat. I managed to build a non-booting kernel because I
thought 64 was a nice power of two, which lead to the kernel blocking when
it tried to actually use or allocate a 2^64 buffer.
Please apply, would've saved me a few hours of debugging.
