Subject: IB/mlx5: Use u64 for UMR length
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b216af408c985092a79472ad10e6f216cb2973fc;p=linux-beck.git

IB/mlx5: Use u64 for UMR length

The fast_registration length is used to convey length for memory
registrations through UMR which can be of any size up to 2^64.

Change the length type to be u64.
