Geert Uytterhoeven a5a16e4352 xsk: Fix umem fill/completion queue mmap on 32-bit
With gcc-4.1.2 on 32-bit:

    net/xdp/xsk.c:663: warning: integer constant is too large for ‘long’ type
    net/xdp/xsk.c:665: warning: integer constant is too large for ‘long’ type

Add the missing "ULL" suffixes to the large XDP_UMEM_PGOFF_*_RING values
to fix this.

    net/xdp/xsk.c:663: warning: comparison is always false due to limited range of data type
    net/xdp/xsk.c:665: warning: comparison is always false due to limited range of data type

"unsigned long" is 32-bit on 32-bit systems, hence the offset is
truncated, and can never be equal to any of the XDP_UMEM_PGOFF_*_RING
values.  Use loff_t (and the required cast) to fix this.

Fixes: 423f38329d ("xsk: add umem fill queue support and mmap")
Fixes: fe2308328c ("xsk: add umem completion queue support and mmap")

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

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.
