When displaying hist triggers, variable references that have the timestamp field flag set are erroneously displayed as common_timestamp rather than the variable reference. Additionally, timestamp expressions are displayed in the same way. Fix this by forcing the timestamp flag handling to follow variable reference and expression handling.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
