IB/core: Add flags for on demand paging support
* Add a configuration option for enable on-demand paging support in the infiniband subsystem (CONFIG_INFINIBAND_ON_DEMAND_PAGING). In a later patch, this configuration option will select the MMU_NOTIFIER configuration option to enable mmu notifiers. * Add a flag for on demand paging (ODP) support in the IB device capabilities. * Add a flag to request ODP MR in the access flags to reg_mr. * Fail registrations done with the ODP flag when the low-level driver doesn't support this. * Change the conditions in which an MR will be writable to explicitly specify the access flags. This is to avoid making an MR writable just because it is an ODP MR. * Add a ODP capabilities to the extended query device verb.
