For _CAN_NAP, I'm guessing its historic, maybe Dan knows why it  
wasn't set.
What happens if you try to set it?  Are there implications at the  
system level
with regards to _CAN_NAP?

Just tested: set CPU_FTR_MAYBE_CAN_DOZE for 82xx, CONFIG_BDI_SWITCH  
is not
defined, echoed 1 to /proc/sys/kernel/powersave-nap - and a 8241 still
runs... I'll try to measure if there's any difference in power
consumption:-))

I'm looking at the CPU_FTR_PPC_LE it varies if we should use  
_PPC_LE vs
_TRUE_LE (or whatever the other one is called).

It would be good for someone to test an 8260 class (826x, 8272,  
etc..) to see if they have any issues.
