struct qedr_alloc_ucontext_resp is a different length in 32 and 64 bit compiles due to implicit compiler padding. The structs alloc_pd_uresp, create_cq_uresp and create_qp_uresp are not padded by the compiler, but in user space the compiler pads them due to the way the core and driver structs are concatenated. Make this padding explicit and consistent for future sanity. The kernel driver can already handle the user buffer being smaller than required and copies correctly, so no compat or ABI break happens from introducing the explicit padding.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
