Jason Wang 231897021c vhost-vdpa: switch to use vmf_insert_pfn() in the fault handler ... commit 0823dc64586ba5ea13a7d200a5d33e4c5fa45950 upstream. remap_pfn_page() should not be called in the fault handler as it may change the vma->flags which may trigger lockdep warning since the vma write lock is not held. Actually there's no need to modify the vma->flags as it has been set in the mmap(). So this patch switches to use vmf_insert_pfn() instead.
