LGTM on my side. Please leave some time for @MaskRay to comment.

For reference, the use of p_vaddr in Bionic's dynamic loader makes sense. At that point Bionic has already mmapped the ELF file into memory at p_vaddr (+ some displacement as shared libraries are position independent) so it is operating on the in-memory representation of the ELF file. LLD is reading directly from the file.
