commit 7f44beadcc11adb98220556d2ddbe9c97aa6d42d upstream.
Putting the cpumask on the stack is deprecated for a long time (since
2d3854a37e), as these can be big. Given that, change the on-stack
allocation of allowed_mask to be dynamically allocated.
Fixes: f011c9cf04c0 ("io_uring/sqpoll: do not allow pinning outside of cpuset")

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.
