Hi David,
Sorry for the inconvenience caused. Yes, "scsi: mpt3sas: Bug fix for big
endian systems." patch was posted to fix sparse warnings.
I missed the testing. Currently we are testing on sparc64 system and soon
I will be reposting the patch based on the findings.
Thanks,
Chaitra

scsi: mpt3sas: Bug fix for big endian systems.
==========
actually breaks big-endian. This driver has been working perfectly
fine for more a decade or so on my sparc64 test systems up until this
point.
If you are just responding to sparse warnings, please do not do that.
What big-endian system did you test this change on?
Meanwhile, I'd like to ask that this change be reverted.
Thank you.

David,
Please let us know what is the issue faced and if its recreating then
share the driver logs with logging_level=0x3f8.
Thanks,
Chaitra

The driver cannot even probe successfully to start scanning for disks
because some busy bit never clears. I think it was in one of the
firmware status registers or the doorbell register.
