ATA_HORKAGE_DMA_RW_ONLY for TORiSAN is verified to be subset of using DMA for ATAPI commands which aren't aligned to 16 bytes. As libata now doesn't use DMA for unaligned ATAPI commands, the horkage is redundant. Kill it. Signed-off-by: NTejun Heo <htejun@gmail.com> Signed-off-by: NJeff Garzik <jeff@garzik.org>

The IDE driver used DMA for ATAPI commands if READ/WRITE command is multiple of sector size or sg command is multiple of 16 bytes. For libata, READ/WRITE sector alignment is guaranteed by the high level driver (sr), so we only have to worry about the 16 byte alignment. This patch makes ata_check_atapi_dma() always request PIO for all data transfer commands which are not multiple of 16 bytes. The following reports are related to this problem. http://bugzilla.kernel.org/show_bug.cgi?id=8605 (confirmed) http://thread.gmane.org/gmane.linux.kernel/476620 (confirmed) https://bugzilla.novell.com/show_bug.cgi?id=229260 (probably) Albert first pointed out the difference between IDE and libata.

When EH gives up after repeated exceptions, it doesn't't clear the PENDING bit on exit which leaves PENDING bit set without EH actually scheduled.

The infamous abnormal status message triggers on not so abnormal cases including empty port and even when it's being triggered on actual errors the info it provides is redundant and out of context - higher level functions will print the info in better safe later anyway. Also, by being triggered all the time, it leads people to think that the abnormality is somehow related to all ATA and system problems they're experiencing and gives owners of healthy systems unfounded doubts about the integrity of the universe.

由 Siddha, Suresh B 提交于
Force irq migration path during cpu offline, is not using proper locks and irq_chip mask/unmask routines. This will result in some races(especially the device generating the interrupt can see some inconsistent state, resulting in issues like stuck irq,..). Appended patch fixes the issue by taking proper lock and encapsulating irq_chip set_affinity() with a mask() before and an unmask() after. This fixes a MSI irq stuck issue reported by Darrick Wong. There are several more general bugs in this area(irq migration in the process context). For example, 1. Possibility of missing edge triggered irq. 2. Reliable method of migrating level triggered irq in the process context. We plan to look and close these in the near future. Eric says: In addition even with the fix from Suresh there is still at least one nasty hardware race in fixup_irqs(). However we exercise that code path rarely enough that we are unlikely to hit it in the real world, and that race seems to have existed since the code was merged. And a fix for that is not coming soon as it is an open investigation area if we can fix irq migration to work outside of irq context or if we have to rework the requirements imposed by the generic cpu hotplug and layer on fixup_irqs(). So this may come up again. Signed-off-by: NSuresh Siddha <suresh.b.siddha@intel.com> Cc: Eric W.
