Should we be using CONFIG_PREEMPT_BKL in the Fedora kernel?

let me double-correct myself: PREEMPT_BKL is indeed default enabled on 
SMP:

 config PREEMPT_BKL
         bool "Preempt The Big Kernel Lock"
         depends on SMP || PREEMPT
         default y
         help

so basically everyone who tests SMP kernels has it.
