From 26635112d4d057c9ea38f6284423a30a41a09240 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Thu, 29 Oct 2015 17:35:40 -0500 Subject: PCI: Make Enhanced Allocation bitmasks more obvious Expand bitmask #defines completely. This puts the shift in the code instead of in the #define, but it makes it more obvious in the header file how fields in the register are laid out. No functional change.
