[ Upstream commit 1ce7d306ea63f3e379557c79abd88052e0483813 ]
struct veth_rq is pretty large, 832B total without debug
options enabled. Since commit under Fixes we try to pre-allocate
enough queues for every possible CPU. Miao Wang reports that
this may lead to order-5 allocations which will fail in production.
Let the allocation fallback to vmalloc() and try harder.
These are the same flags we pass to netdev queue allocation.

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.
