Yi Liu 2001e6eabf RDMA/uverbs: Add __GFP_NOWARN to ib_uverbs_unmarshall_recv() kmalloc
[ Upstream commit 58b604dfc7 ]

Since wqe_size in ib_uverbs_unmarshall_recv() is user-provided and already
validated, but can still be large, add __GFP_NOWARN to suppress memory
allocation warnings for large sizes, consistent with the similar fix in
ib_uverbs_post_send().

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.

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.
