Having two overloads of target_read_auxv that don't have the same goals is confusing. Rename the one that reads from an explicit target_ops to target_read_auxv_raw. Also, it occured to me that the non-raw version could use the raw version, that reduces duplication a bit. Change-Id: I28e5f7cecbfcacd0174d4686efb3e4a23b4ad491
