[linux-next][bisected c7c133f3][gcc 4.8.5] build fail with error: first argument to‘__builtin_choose_expr’ not a constant

Greetings,

Today's next kernel fails to build with gcc 4.8.5 on powerpc machine.


./include/linux/jiffies.h: In function ‘jiffies_delta_to_clock_t’:
./include/linux/kernel.h:855:2: error: first argument to ‘__builtin_choose_expr’ not a constant
  __builtin_choose_expr(__builtin_constant_p(x) &&  \
  ^
./include/linux/kernel.h:867:19: note: in expansion of macro ‘__max’
 #define max(x, y) __max(typeof(x), typeof(y), x, y)

Machine Type: Power8 Baremetal
gcc: 4.8.5


Builds fine when below patch is reverted
c7c133f3 kernel.h: skip single-eval logic on literals in min()/max()
