[PATCH] ARM: 2760/1: Add a warning on dynamic tick timekeeping on some platforms

Browse source 
Patch from Tony Lindgren

This patch was suggested by RMK, and adds a warning on the accuracy
of timekeeping when using dynamic tick on some platforms. Depending
on the timer implementation, dynamic tick may affect the accuracy of
timekeeping.
Currently at least OMAP is known to have accurate timekeeping with
dynamic tick.

Alternatively, if you want dynamic tick automatically enabled
during boot, pass "dyntick=enable" via the kernel command string.
Please note that dynamic tick may affect the accuracy of
timekeeping on some platforms depending on the implementation.
