Revision d45364e6d4b7125c9d2abac6f63eec509316195f authored by Prasad Singamsetty on 14 November 2017, 23:13:49 UTC, committed by Michael Roth on 21 June 2018, 01:45:05 UTC 
intel-iommu: Redefine macros to enable supporting 48 bit address width
 
The current implementation of Intel IOMMU code only supports 39 bits
host/iova address width so number of macros use hard coded values based
on that. This patch is to redefine them so they can be used with
variable address widths. This patch doesn't add any new functionality
but enables adding support for 48 bit address width.
