From: Ira Weiny <ira.weiny@xxxxxxxxx> kmap() is being deprecated and will break uses of device dax after PKS protection is introduced.[1] These kmap() usages don't need to be global and work fine as thread local mappings. Replace these kmap() calls with kmap_local_page() which is more appropriate. The only final use of kmap() in the RDMA subsystem is in the qib driver which is pretty old at this point. The use is pretty convoluted and I doubt systems using that driver are using persistent memory. So it is left as is. If this is a problem I can dig into converting it as well.
