Revision e4785b0633574a607daaa04bf2fe43550055194f authored by Steven L. Roberts on 10 May 2017, 19:58:13 UTC, committed by Doug Ledford on 01 June 2017, 21:03:40 UTC
The Omni-Path adapter driver fails to load on the ppc64le platform due to invalid PCI setup. This patch makes the PCI configuration more robust and will fix 64 bit addressing for ppc64le.
