powerpc/pseries: Enable CMO feature during platform setup
For Cooperative Memory Overcommitment (CMO), set the FW_FEATURE_CMO flag in powerpc_firmware_features from the rtas ibm,get-system-parameters table prior to calling iommu_init_early_pSeries. With this, any CMO specific functionality can be controlled by checking: firmware_has_feature(FW_FEATURE_CMO) Signed-off-by: Robert Jennings <rcj@linux.vnet.ibm.com> Acked-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
