KVM: PPC: Move KVM trampolines before __end_interrupts
When using a relocatable kernel we need to make sure that the trampline code
and the interrupt handlers are both copied to low memory. The only way to do
this reliably is to put them in the copied section.
This patch should make relocated kernels work with KVM.
