Resets are done with port frozen but some controllers still issue interrupts during reset and they may end up recording error conditions in ehi leading to unnecessary EH retrials. This patch makes ata_eh_reset() clear ehi on reset completion. As reset is the most severe recovery action, there's nothing to lose by clearing ehi on its completion. Signed-off-by:

Call the ->freeze() hook before aborting qc's, because some hardware requires special handling prior to accessing the taskfile registers (for diagnosis/analysis/reset). Most notably, hardware may wish to disable the DMA engine or interrupts in the ->freeze() hook. Signed-off-by:

Commit log for commit 517d3cc1 ("[libata] ata_piix: Enable parallel scan") says: This patch turns on parallel scanning for the ata_piix driver. This driver is used on most netbooks (no AHCI for cheap storage it seems). The scan is the dominating time factor in the kernel boot for these devices; with this flag it gets cut in half for the device I used for testing (eeepc). Alan took a look at the driver source and concluded that it ought to be safe to do for this driver. Alan has also checked with the hardware team. and it is all true but once we put all things together additional constraints for PATA controllers show up (some hardware registers have per-host not per-port atomicity) and we risk misprogramming the controller. I used the following test to check whether the issue is real: @@ -736,8 +736,20 @@ static void piix_set_piomode(struct ata_ (timings[pio][1] << 8); } pci_write_config_word(dev, master_port, master_data); - if (is_slave) + if (is_slave) { + if (ap->port_no == 0) { + u8 tmp = slave_data; + + while (slave_data == tmp) { + pci_read_config_byte(dev, slave_port, &tmp); + msleep(50); + } + + dev_printk(KERN_ERR, &dev->dev, "PATA parallel scan " + "race detected\n"); + } pci_write_config_byte(dev, slave_port, slave_data); + } /* Ensure the UDMA bit is off - it will be turned back on if UDMA is selected */ and it indeed triggered the error message. Lets fix all such races by adding an extra locking to ->set_piomode and ->set_dmamode methods for PATA controllers. [ Alan: would be better to take the host lock in libata-core for these cases so that we fix all the adapters in one swoop.

The lack of a proper LRU was partially worked around by taking the fence from the object containing the oldest seqno. But if there are multiple objects inactive, then they don't have seqnos and the first fence reg among them would be chosen. If you were trying to copy data between two mappings, this could result in each page fault stealing the fence from the other argument, and your application hanging. https://bugs.freedesktop.org/show_bug.cgi?id=23566 https://bugs.freedesktop.org/show_bug.cgi?id=23220 https://bugs.freedesktop.org/show_bug.cgi?id=23253 https://bugs.freedesktop.org/show_bug.cgi?id=23366 Cc: Stable Team <stable@kernel.org> Signed-off-by:
