Other RAID drivers (eg: aacraid) makes the assumption that commands in these
paths (INQUIRY, READ CAPACITY, MODE SENSE etc spoofing) are single scatter
gather elements and have yet to be bitten. I agree with Fujita-san about the
practical unlikelihood. The fix does not incur any change in c

Provide a facility to use the request_firmware() interface to get a SAS
address from userspace. This can be used by SAS LLDDs that cannot
obtain the address from the host adapter.

If we send an ABORT_TASK ascb that doesn't return within the timeout period,
we should not free that ascb because the sequencer is still holding onto it.
Hopefully it will fix what James Bottomley describes below:

If the aic94xx chip doesn't have a SAS address in the chip's flash memory,
make libsas get one for us.
