[ Upstream commit a1ebf7718ee31501d2d2ee3af1716e0084c81926 ] Test that the new expression builtin returns a match when the current escaped CPU ID is given, and that it doesn't match when "0x0" is given. The CPU ID in test__expr() has to be changed to perf_pmu__getcpuid() which returns the CPU ID string, rather than the raw CPU ID that get_cpuid() returns because that can't be used with strcmp_cpuid_str(). It doesn't affect the is_intel test because both versions contain "Intel".

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.
