Bug Description
SRU Justification
[Impact]
On systems with a broken BIOS that fail to program the APICID_TAG_MAP for DCA,
the dmaengine will print a warning, with stack trace, to the kernel log,
which just adds extra noise to the log and impacts testing on some platforms,
mostly on the older side that will most likely not receive an update to their BIOS.
[Fix]
A patch from upstream linux changes the call of WARN_TAINT_ONCE() to pr_warn_once()
and add_taint(). pr_warn_once() will not invoke a warning in the kernel and instead
just print the associated message.
[Test Case]
The ubuntu_boot log_check test on an affected node, such as fili:amd64.
[Where problems could occur]
Chance of regression is very low to minimal with this change.
