commit 7c03e7035ac1cf2a6165754e4f3a49c2f1977838 upstream.
Now that the vDSO implementation of clock_gettime() is getting
reworked, add a selftest for it. This tests that its output is
consistent with the syscall version.
This is marked for stable to serve as a test for commit
715bd9d12f84 ("x86/vdso: Fix asm constraints on vDSO syscall fallbacks")

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.
