Request to include the following patch into stable for linux-4.19 and 
linux-4.20:

scsi: mpt3sas: fix memory ordering on 64bit writes
commit: 23c3828aa2f8


Commit 09c2f95ad404 introduced a bug apparent on powerpc64 systems 
causing SAS HBAs relying on mpt3sas to drop from the PCIe bus under 
load, rendering those devices virtually useless.

As linux-4.19 is a longterm kernel, the bug would affect those systems 
for a long time otherwise.
