Subject[PATCH 2/8] Consolidate all .h lines at front of intel-iommu.c file
Date

In intel-iommu.c, move downward the few lines near the
front that should not move to an intel-iommu-private.h
file (mostly data-item definitions) This leaves a
consolidated block of the lines that would move to an
intel-iommu-private.h file at the front of the file.
