Subject[PATCH v2 01/17] KVM: async_pf: Move struct kvm_async_pf around
Date
This moves the definitions of "struct kvm_async_pf" and the related
functions after "struct kvm_vcpu" so that newly added inline function
can dereference "struct kvm_vcpu" properly. Otherwise, the unexpected
build error will be raised:

error: dereferencing pointer to incomplete type ‘struct kvm_vcpu’
return !list_empty_careful(&vcpu->async_pf.done);
^~

The sepator between type and field is replaced by tab for "struct
kvm_async_pf" since we're here. This is preparatory work for adding
new inline function for next patch. This shouldn't cause logical
changes.
