kisskb.ellerman.id.au says it's broken there, so it's applied.

While I've got your attention, there was another build break on ia64 in
linux-next, caused by removal of smp_call_function_mask.

Thanks,
Rusty.

Subject: ia64: convert last user of smp_call_function_mask

smp_call_function_many is the new version: it takes a pointer.  Also,
use mm accessor macro while we're changing this.
