On the way there a number of other things were once again noticed. All patches have now been tested on a Fam15 and a Fam17 system. 01: don't blindly allocate interrupt remapping tables 02: make phantom functions share interrupt remapping tables 03: x86/PCI: read maximum MSI vector count early 04: replace INTREMAP_ENTRIES 05: restrict interrupt remapping table sizes 06: tidy struct ivrs_mappings 07: allocate one device table per PCI segment 08: pre-fill all DTEs right after table allocation Jan
