[PATCH] Move LOG_BUF_SHIFT to a more sensible place

[Alistair John Strachan <s0348365@sms.ed.ac.uk>]

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.
