Cover letter [PATCH v1 0/6] QEMU: kvm: cleanup kvm_slot handling

We can heavily simplify the kvm_slot code. Flatview will make sure that we don't have to deal with overlapping slots. E.g. when a memory section is resized, we are first notified about the removal and then about the new memory section.

So basically, we can directly always map one memory section to one kvm slot (if the fixed up size is > 0).

RFC -> v1:

kvm: factor out alignment of memory section
kvm: use start + size for memory ranges
kvm: we never have overlapping slots in kvm_set_phys_mem()
kvm: kvm_log_start/stop are only called with known sections
kvm: kvm_log_sync() is only called with known memory sections
