ahc_pci.c: Bring back the AHC_ALLOW_MEMIO option at least until the memory mapped I/O problem on the SuperMicro 370DR3 is better understood. aic7xxx.c: If we see a spurious SCSI interrupt, attempt to clear it and continue by unpausing the sequencer. Change the interface to ahc_send_async(). Some async messages need to be broadcast to all the luns of a target or all the targets of a bus. This is easier to achieve by passing explicit channel, target, and lun parameters instead of attempting to construct a device info struct to match. Filter the sync parameters for the PPR message in exactly the same way we do for an old fashioned SDTR message. Correct some typos and correct a panic message. Handle rejected PPR messages. In ahc_handle_msg_reject(), let ahc_build_transfer_msg() build any additional transfer messages instead of doing this inline. aic7xxx.h: Increase the size of both msgout_buf and msgin_buf to better accomodate PPR messages. aic7xxx_freebsd.c: Update for change in ahc_send_async() parameters. aic7xxx_freebsd.h Update for change in ahc_send_async() parameters. Honor AHC_ALLOW_MEMIO. aic7xxx_pci.c: Check the error register before going into full blown PCI interrupt handling. This avoids a few costly PCI configuration space reads when we run our PCI interrupt handler because another device sharing our interrupt line is more active than we are. Also unpause the sequencer after processing a PCI interrupt.
