On hybrid platforms the CPU maps are often disjoint. Rather than copy CPUs and trim, compute the number of common CPUs, if none early exit, otherwise copy in an sorted order. This avoids memory allocation in the disjoint case and avoids a second malloc and useless sort in the previous trim cases.

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 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.
