The problem was that link_shadow_page did not take an kvm_mmu parameter,
so I don't know where to find this link_shadow_page_set_bits. So either
I pass the pointer to the entire kvm_mmu to link_shadow_page, or I just
pass the only field which I need... I thought that passing the single
field I need was cleaner - but I can easily change it if you prefer to
pass the kvm_mmu.
Thanks,
Nadav.
