5.27 32-bit RDMA packages are installed when upgrading a system with rdma-core installed

When upgrading from a system prior to Oracle Linux 7 Update 4, where the rdma-core.noarch package is installed, 32-bit versions of the packages and many dependencies are also installed, unnecessarily. This is because the original version of the package is obsoleted and during upgrade the package is replaced with both the rdma-core.i686 and rdma-core.x86_64 versions of the package, along with those packages' dependencies.

To work around the issue, run the yum update command with the --exclude=\*.i686 option:

# yum update --exclude=\*.i686
