Subject: virt/kvm: Use vma_lookup() instead of find_vma_intersection()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=1de0b1423e99ab80eb414558db4def95ed88bfda;p=users%2Fjedix%2Flinux-maple.git

virt/kvm: Use vma_lookup() instead of find_vma_intersection()

vma_lookup() finds the vma of a specific address with a cleaner
interface and is more readable.
