Sorry David, I just noticed you weren't in the "To:" of this serie, but I won't
forget you for the v3 I need to release anyway

Bah this one is not good enough.

First, machine_is_*() is not defined if CONFIG_ARM=n, and this part is not under
a #ifdef CONFIG_ARM.

Moreover, I think it is a good occasion to go further, and :
- enhance smc91x_platdata and add a pxa_u16_align4 boolean
- transform this statement into :
lp->half_word_align4 = lp->cfg.pxa_u16_align4

This will remove the machine_*() calls from the smc91x driver, which looks a
good move, doesn't it ?
