Backport arm64 write combining support optimization to RHEL 9.5
JIRA: https://issues.redhat.com/browse/RHEL-43402
Note: I skipped one commit from the series: 2b7a5e1fe0223 net: hns3: Remove io_stop_wc() calls after __iowrite64_copy() because it exclusively touches code that has not yet been backported
