      [PATCH] sched: tidy up left over smpnice code · 5a4f3ea7
      Peter Williams authored
      1. The only place that RTPRIO_TO_LOAD_WEIGHT() is used is in the call to
      move_tasks() in the function active_load_balance() and its purpose here
      is just to make sure that the load to be moved is big enough to ensure
      that exactly one task is moved (if there's one available).  This can be
      accomplished by using ULONG_MAX instead and this allows
      RTPRIO_TO_LOAD_WEIGHT() to be deleted.
      
      2. This, in turn, allows PRIO_TO_LOAD_WEIGHT() to be deleted.
      
      3. This allows load_weight() to be deleted which allows
      TIME_SLICE_NICE_ZERO to be deleted along with the comment above it.

      genirq: temporary fix for level-triggered IRQ resend · 0fc4969b
      Thomas Gleixner authored
      Marcin Slusarz reported a ne2k-pci "hung network interface" regression.
      
      delayed disable relies on the ability to re-trigger the interrupt in the
      case that a real interrupt happens after the software disable was set.
      In this case we actually disable the interrupt on the hardware level
      _after_ it occurred.
      
      On enable_irq, we need to re-trigger the interrupt. On i386 this relies
      on a hardware resend mechanism (send_IPI_self()).
      
      Actually we only need the resend for edge type interrupts. Level type
      interrupts come back once enable_irq() re-enables the interrupt line.
      
      I assume that the interrupt in question is level triggered because it is
      shared and above the legacy irqs 0-15:
      
      	17:         12   IO-APIC-fasteoi   eth1, eth0
      
      Looking into the IO_APIC code, the resend via send_IPI_self() happens
      unconditionally. So the resend is done for level and edge interrupts.
      This makes the problem more mysterious.
      
      The code in question lib8390.c does
      
      	disable_irq();
      	fiddle_with_the_network_card_hardware()
      	enable_irq();
      
      The fiddle_with_the_network_card_hardware() might cause interrupts,
      which are cleared in the same code path again,
      
      Marcin found that when he disables the irq line on the hardware level
      (removing the delayed disable) the card is kept alive.
      
      So the difference is that we can get a resend on enable_irq, when an
      interrupt happens during the time, where we are in the disabled region.
