When one llseek's past the end of the file and then writes, every page past the previous end of the file should be cleared. Trevor found that the code, as is, does not assure that the very last page is always cleared. This patch takes care of that. Signed-off-by:

Recent changes in eCryptfs have made it possible to get to ecryptfs_setattr() with an uninitialized crypt_stat struct. This results in a wide and colorful variety of unpleasantries. This patch properly initializes the crypt_stat structure in ecryptfs_setattr() when it is necessary to do so. Signed-off-by:

This patch fixes the processes involved in wiping regions of the data during truncate and write events, fixing a kernel hang in 2.6.22-rc4 while assuring that zero values are written out to the appropriate locations during events in which the i_size will change. The range passed to ecryptfs_truncate() from ecryptfs_prepare_write() includes the page that is the object of ecryptfs_prepare_write(). This leads to a kernel hang as read_cache_page() is executed on the same page in the ecryptfs_truncate() execution path. This patch remedies this by limiting the range passed to ecryptfs_truncate() so as to exclude the page that is the object of ecryptfs_prepare_write(); it also adds code to ecryptfs_prepare_write() to zero out the region of its own page when writing past the i_size position. This patch also modifies ecryptfs_truncate() so that when a file is truncated to a smaller size, eCryptfs will zero out the contents of the new last page from the new size through to the end of the last page.

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:

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.

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. Make it a DPRINTK and save the universe. Signed-off-by:

Siddha, Suresh B authored
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:

This one changes the SN2 specific PCI drivers to use ioremap() for obtaining the real address to access for the PCI registers instead of manually calculating them with __IA64_UNCACHED_OFFSET. The patch should have no real change when running on a normal Linux kernel, but when running as a paravirtualized it is needed. Signed-off-by:

Correct the validation check on these fields to check for both stack areas.
