      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.

      pata_sis: fix MWDMA for <= UDMA66 chipsets and UDMA for UDMA33 chipsets · 4761c06c
      Bartlomiej Zolnierkiewicz authored
      * Fix MWDMA timings setup in sis_old_set_dmamode() and sis_66_set_dmamode().
      
        The old timings were overclocked (even worse behavior than sis5513 IDE driver
        which depends on BIOS to program correct timings), the new timings are taken
        from the datasheet (they match timings from ATA spec).
      
      * Fix UDMA timings setup in sis_old_set_dmamode().
      
        Misplaced pci_write_config_word() call resulted in UDMA timings never
        being set.
      
      * Fix comments for sis_133_early_set_dmamode() and sis_133_set_dmamode():
        - only the former function handles early SiS 961 bridges
        - both functions lack MWDMA timings setup
      
      * Fix typos in sis_100_set_piomode() and sis_133_set_piomode() comments.
      
      * Bump driver version.

      Seems nobody else is checking/testing this case as it keeps getting
      horked.
      
      If we have no BAR4 mapping on an SFF controller this is *NOT* an error,
      it just means it isn't doing BMDMA.

      Fix WARN_ON() on bitfield ops · 8d4fbcfb
      Linus Torvalds authored
      Alexey Dobriyan noticed that the new WARN_ON() semantics that were
      introduced by commit 684f9783 (to also
      return the value to be warned on) didn't compile when given a bitfield,
      because the typeof doesn't work for bitfields.
      
      So instead of the typeof trick, use an "int" variable together with a
      "!!(x)" expression, as suggested by Al Viro.
      
      To make matters more interesting, Paul Mackerras points out that that is
      sub-optimal on Power, but the old asm-coded comparison seems to be buggy
      anyway on 32-bit Power if the conditional was 64-bit, so I think there
      are more problems there.
      
      Regardless, the new WARN_ON() semantics may have been a bad idea.  But
      this at least avoids the more serious complications.
