    Fix sign extension bug on x86_64 system.
    
    In XF86DGAGetVideoLL(), we pass offset param as 'int' type, but
    later we cast it to 'unsigned long' in calling MapPhysAddress().
    This causes page table error on x86_64 system like below:
    
    dga: Corrupted page table at address 2b9712b1b000
    PGD 702a4067 PUD 6f830067 PMD 6f864067 PTE ffffffff80040027
