Subject: [patch V2 02/17] ARM: vdso: Remove unused function

From: Thomas Gleixner <tglx@...utronix.de>

The function is nowhere used. Aside of that this check should only cover
the high resolution parts of the VDSO which require a VDSO capable
clocksource and not the complete functionality as the name suggests. Will
be replaced with something more useful.
