Hello all,
The following patch removes some unneccessary (it seems) typedefs, and
adds in the pci_set_dma_mask() check mentioned in
Documentation/DMA-mapping.txt . Please review.
Regards,
Frank

Did your Buslogic patch ever get included? I'm still
getting errors compiling 2.5.x as of .26 last night:
BusLogic.c:32: #error Please convert me to Documentation/DMA-mapping.txt
BusLogic.c: In function `BusLogic_DetectHostAdapter':
BusLogic.c:2841: warning: long unsigned int format, BusLogic_IO_Address_T arg (arg 2)
BusLogic.c: In function `BusLogic_QueueCommand':

BusLogic.c: In function `BusLogic_BIOSDiskParameters':

BusLogic.c:4141: warning: assignment makes pointer from integer without a cast
make[2]: *** [BusLogic.o] Error 1
Given that your patch was against .24, I would guess
it should be "relatively" safe against a .26 since it's
only driver code that everyone else seems to be ignoring.

The driver needs more than just the dma mask set.

Probably didn't get in because the driver is still not compliant with the
new kernel requirements for PCI/DMA

That probably wants sg_dma_address()

Well its not the friendliest code either ;)
