Move LOG_BUF_SHIFT to a more sensible place
Several people have observed that perhaps LOG_BUF_SHIFT should be in a more obvious place than under DEBUG_KERNEL. Under some circumstances (such as the PARISC architecture), DEBUG_KERNEL can increase kernel size, which is an undesirable trade off for something as trivial as increasing the kernel log buffer size. Instead, move LOG_BUF_SHIFT into "General Setup", so that people are more likely to be able to change it such a circumstance that the default buffer size is insufficient.
