[PATCH 0/2] timer: make deferrable cpu unbound timers really not bound to a cpu

[Prasad Sodagudi <psodagud@codeaurora.org>]

These patches introduce support for global deferrable timers and this feature is very useful
for the mobile chipsets. There was a discussion on global deferrable timer discussion - [1]
and thomas raised cacheline bouncing problem. I am thinking that, that problem is addressed
on later patches problem as much as possible. Global deferrable timers runs on the
tick_do_timer_cpu to avoid cacheline bouncing problem during the execution of timers.
