clock_was_set() unconditionaly invokes retrigger_next_event() on all online CPUs. This was necessary because that mechanism was also used for resume from suspend to idle which is not longer the case. The bases arguments allows the callers of clock_was_set() to hand in a mask which tells clock_was_set() which of the hrtimer clock bases are affected by the clock setting. This mask will be used in the next step to check whether a CPU base has timers queued on a clock base affected by the event and avoid the SMP function call if there are none. Add a @bases argument, provide defines for the active bases masking and fixup all callsites.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
