commit 1af6239d1d3e61d33fd2f0ba53d3d1a67cc50574 upstream. With the advent of CFI it is no longer acceptible to cast function pointers.

The robot complains thusly:

kernel-events-core.c:warning:cast-from-int-(-)(struct-perf_cpu_pmu_context-)-to-remote_function_f-(aka-int-(-)(void-)-)-converts-to-incompatible-function-type
