This fixes the output of rps_default_mask and flow_limit_cpu_bitmap when the CPU count is > 448, as it was truncated. The underlying values are actually stored correctly when writing to these sysctl but displaying them uses a fixed length temporary buffer in dump_cpumask. This buffer can be too small if the CPU count is > 448. Fix this by dynamically allocating the buffer in dump_cpumask, using a guesstimate of what we need.

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 reStructuredText 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.
