Hi all,

While compiling Linus' tree, a powerpc-allmodconfig build (and others)
with gcc 4.9 failed like this:

drivers/net/ethernet/microchip/sparx5/sparx5_netdev.c: In function 'ifh_encode_bitfield':
include/linux/compiler_types.h:328:38: error: call to '__compiletime_assert_431' declared with attribute error: Unsupported width, must be <= 40
  _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__)
                                      ^
include/linux/compiler_types.h:309:4: note: in definition of macro '__compiletime_assert'
    prefix ## suffix();    \

  compiletime_assert(width <= 40, "Unsupported width, must be <= 40");
  ^

Caused by commit

  f3cad2611a77 ("net: sparx5: add hostmode with phylink support")

I guess this is caused by the call to ifh_encode_bitfield() not being
inlined.
