Subject: dtrace: percpu: move from __get_cpu_var() to this_cpu_ptr()
X-Git-Tag: v4.1.12-111.0.20170907_2225~3^2~3^2~80

dtrace: percpu: move from __get_cpu_var() to this_cpu_ptr()

__this_cpu_add() was removed.  Modules now use a regular atomic_t for the
reference counter, so atomic_add() can be used.
