That requires to fix all call sites in ia64 and that's why I didn't. But
I didn't express clearly, I meant remove the if(...) statement from apic_ack_irq(), it doesn't require to fix the call sites in ia64.
I put the check there on purpose as I explained in the changelog:
Making the invocation of irq_move_irq() conditional avoids the out of line call if the pending bit is not set.
Thanks,
