if __ARCH_WANT_INTERRUPTS_ON_CTXSW is set to 1 for arm you can turn this
into
p->hardirqs_enabled = __ARCH_WANT_INTERRUPTS_ON_CTXSW + 0;
and save the ifdef ;)
#ifdef is actually really evil. It's much cleaner to use #if and make
sure everything defines either 0 or 1. Partially because it often makes
you not have to add an #if at all, but also because it makes it
immediately obvious if some definition was missed.
