Subject: [PATCH v6 25/28] sfc: specify no dax when cxl region is created

From: Alejandro Lucero <alucerop@....com>

The CXL memory should not be used by the host in any case except for
what the driver allows. Tell the cxl core to not create a DAX device
using the avoid dax at region creation time.
