Signed-off-by: Tejun Heo Signed-off-by: Jeff Garzik commit b9a4197e266a40d5d1d16c9fb2a852cf10743afe Author: Tejun Heo Date: Wed Jun 27 02:48:43 2007 +0900 libata: use PIO for non-16 byte aligned ATAPI commands 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.

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: Suresh Siddha Cc: Eric W. Biederman Reported-and-tested-by: Darrick Wong Cc: Andi Kleen Acked-by: Rafael J.

This patch (as913) by Oleg Nesterov makes the code use allow_signal() instead of sigprocmask().

If we have a signal handler that has used the floating-point registers, and it happens to context-switch to another task while copying the interrupted floating-point state from the user stack into the thread struct (e.g. because of a page fault, or because it gets preempted), the context switch code will think that the FP registers contain valid FP state that needs to be copied into the thread_struct, and will thus overwrite the values that the signal return code has put into the thread_struct. This can occur because we clear the MSR bits that indicate the presence of valid FP state after copying the state into the thread_struct. To fix this we just move the clearing of the MSR bits to before the copy. A similar potential problem also occurs with the Altivec state, and this fixes that in the same way.

This adds a check for tv being NULL so that it doesn't SEGV.
