This is wrong. Should it be one line up? Note the else...

>  #else

here ^^^

i.e. you appear to be changing
CONFIG_KVM_GUEST:
	CAC_BASE=0x40000000
!CONFIG_KVM_GUEST:
	CAC_BASE=0x80000000

to:

CONFIG_KVM_GUEST:
	!CAC_BASE:
		CAC_BASE=0x40000000
	CAC_BASE:
		CAC_BASE=0x80000000
!CONFIG_KVM_GUEST:
	(nothing)

Cheers
James
