To: Andrew Morton, linux-kernel
This properly indents the kernel hacking menu.
Move LOG_BUF_SHIFT into kernel hacking menu (it already depended on DEBUG_KERNEL).
Add DEBUG_KERNEL dependency to EARLY_PRINTK, DEBUG_PREEMPT and FRAME_POINTER.
Remove overlong dependency, which included practically every arch.
Merge the two MAGIC_SYSRQ menu entries.
Remove unnecessary "default n" options.

Enabling this option will pass "-Os" instead of "-O2" to gcc
