Description of problem:
When using a RHEL7.1 system to install docker, it fails with a missing libdevmapper dependency. 

Version-Release number of selected component (if applicable):
RHEL: 7.1
Docker: 1.8.2-10
device-mapper-libs: libdevmapper.so.1.02(DM_1_02_97)

How reproducible:
Install a RHEL 7.1 system, lock it to 7.1 using "subscription-manager release" then attempt a "yum install docker".

Steps to Reproduce:
1. Install RHEL 7.1
2. Use "subscription-manager release --set=7.1" to lock it in on 7.1
3. Use "yum install docker" to see the error in dependencies

Actual results:
# yum install docker

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest


Expected results:
Docker should install A_OK on RHEL 7.1
