RDMA/efa: Fix unsupported page sizes in device
[ Upstream commit 866422cdddcdf59d8c68e9472d49ba1be29b5fcf ] Device uses 4KB size blocks for user pages indirect list while the driver creates those blocks with the size of PAGE_SIZE of the kernel. On kernels with PAGE_SIZE different than 4KB (ARM RHEL), this leads to a failure on register MR with indirect list because of the miss communication between driver and device. Fixes: 40909f664d27 ("RDMA/efa: Add EFA verbs implementation") Link: https://lore.kernel.org/r/20230511115103.13876-1-ynachum@amazon.com Reviewed-by: Firas Jahjah <firasj@amazon.com> Reviewed-by: Michael Margolin <mrgolin@amazon.com> Signed-off-by: Yonatan Nachum <ynachum@amazon.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
