In commit c1fe190c0672 ("powerpc: Add force enable of DAWR on P9
option") the following piece of code was added:
smp_call_function((smp_call_func_t)set_dawr, &null_brk, 0);
Since GCC 8 this trigger the following warning about incompatible
function types:
arch/powerpc/kernel/hw_breakpoint.c:408:21: error: cast between incompatible
function types from 'int (*)(struct arch_hw_breakpoint *)' to 'void (*)(void
*)' [-Werror=cast-function-type]
Cast the function to an intermediate (void*) to make the compiler loose
knowledge about actual type.
Fixes: c1fe190c0672 ("powerpc: Add force enable of DAWR on P9 option")
