Some machines are spending minutes of CPU time during suspend in stupid O(n^2)

arch/arm/common/sa1111.c: In function `sa1111_suspend':
arch/arm/common/sa1111.c:816: warning: assignment from incompatible pointer type

This is a rather annoying, and IMHO pointless warning.  First question:
what is the reasoning for using an array of unsigned bytes here?  Are we
expecting to power manage devices which only have byte wide registers?

In reality, devices have half-word and word sized registers as well, which
means that dev->power.saved_state actually points to device specific data
(or even device driver specific data) for the device.  As such, it makes
far more sense for this to be a 'void *'.

I'd rather not go around the ARM kernel tree adding pointless casts to 'u8
*' and back again because the wrong type for this was picked in the
structure definition, so here's a patch which changes this to void *.

With clustered mode and AMD's big flat APIC mode there is no reason anymore to

Scheduler support for AMD CMP

AMD dual core looks like HT but isn't really.  Hide it from the scheduler. 
This works around problems with the domain scheduler.  Also probably gives
slightly better scheduling and disables SMT nice which is harmful on dual
