...GES} were pointlessly defined to plain numbers (making it unobvious why they have these values, and making the latter non-portable) - MAX_MSIX_TABLE_PAGES was also off by one (failing to account for a non-zero table offset); this was also affecting host MSI-X code - struct msixtbl_entry''s table_flags[] was one element larger than necessary due to improper open-coding of BITS_TO_LONGS() - msixtbl_read() unconditionally accessed the physical table, even though the data was only needed in a quarter of all cases - various calculations were done unnecessari...
