The issue is maintaining mappings for 32-bit PCI devices. If you only want

Wow, that is a great news, I do not known if my adaptec 3045e raid
card is a 64bit device, but if I only want to support 64bit devices,
Is there a quick fix for it?
I don't know. You could try to make all DMA accesses go via BAR2. That
would break many 32-bit devices though.
