This patch (as810c) copies a minimum of 36 bytes of INQUIRY data, even if the device claims that not all of them are valid. Often badly behaved devices put plausible data in the Vendor, Product, and Revision strings but set the Additional Length byte to a small value. Using potentially valid data is certainly better than allocating a short buffer and then reading beyond the end of it, which is what we do now. Signed-off-by:

While testing kernel on machine with "irqpoll" option I've caught such a lockup: __do_IRQ() spin_lock(&desc->lock); desc->chip->ack(); /* IRQ is ACKed */ note_interrupt() misrouted_irq() handle_IRQ_event() if (...) local_irq_enable_in_hardirq(); /* interrupts are enabled from now */ ... __do_IRQ() /* same IRQ we've started from */ spin_lock(&desc->lock); /* LOCKUP */ Looking at misrouted_irq() code I've found that a potential deadlock like this can also take place: 1CPU: __do_IRQ() spin_lock(&desc->lock); /* irq = A */ misrouted_irq() for (i = 1; i < NR_IRQS; i++) { spin_lock(&desc->lock); /* irq = B */ if (desc->status & IRQ_INPROGRESS) { 2CPU: __do_IRQ() spin_lock(&desc->lock); /* irq = B */ misrouted_irq() for (i = 1; i < NR_IRQS; i++) { spin_lock(&desc->lock); /* irq = A */ if (desc->status & IRQ_INPROGRESS) { As the second lock on both CPUs is taken before checking that this irq is being handled in another processor this may cause a deadlock. This issue is only theoretical. I propose the attached patch to fix booth problems: when trying to handle misrouted IRQ active desc->lock may be unlocked.

Fix MSPEC driver to build for non SN2 enabled configs as the driver should work in cached and uncached modes (no fetchop) on these systems. In addition make MSPEC select IA64_UNCACHED_ALLOCATOR, which is required for it and move it to arch/ia64/Kconfig to avoid warnings on non ia64 architectures running allmodconfig. Once the Kconfig code is fixed, we can move it back. Signed-off-by:

The PCI sysfs attributes are created after the initial PCI bus scan. With the addition of more return value checking and assertions in the device and sysfs layers we now can get dumps like this on sparc64: [ 20.135032] Call Trace: [ 20.135042] [0000000000537f88] pci_remove_bus_device+0x30/0xc0 [ 20.135076] [000000000078f890] pci_fill_in_pbm_cookies+0x98/0x440 [ 20.135109] [000000000042e828] sabre_scan_bus+0x230/0x400 [ 20.135139] [000000000078c710] pcibios_init+0x58/0xa0 [ 20.135159] [0000000000416f14] init+0x9c/0x2e0 [ 20.135190] [0000000000417a50] kernel_thread+0x38/0x60 [ 20.135211] [0000000000417170] rest_init+0x18/0x40 [ 20.135514] PCI0(PBMB): Bus running at 33MHz It's triggering because removal of the "config" PCI sysfs file for the device fails. On sparc64, after probing the device, we'll delete the PCI device via pci_remove_bus_device() if we cannot find the firmware device tree node corresponding to it. This is fine, but at this point the sysfs files for the PCI device won't be setup yet. So we should not try to do anything in pci_remove_sysfs_dev_files() if pci_sysfs_init() has not run yet.

I didn't test it personally since I don't have this card, but A16AR uses the same interface and that one certainly does work perfectly (see the next patch). This patch was originally sent in http://marc.theaimsgroup.com/?l=linux-video&m=114743413825375&w=2 https://www.redhat.com/mailman/private/video4linux-list/2006-May/msg00103.html but never got applied. This version has some trivial modifications and drops the weird gpio hack (it's not clear what practical purpose does it serve). Signed-off-by:

The previous fixes for the use after free in xfs_iunpin left a nasty log deadlock when xfslogd unpinned the inode and dropped the last reference to the inode. the ->clear_inode() method can issue transactions, and if the log was full, the transaction could push on the log and get stuck trying to push the inode it was currently unpinning. To fix this, we provide xfs_iunpin a guarantee that it will always have a valid xfs_inode <-> linux inode link or a particular flag will be set on the inode. We then use log forces during lookup to ensure transactions are completed before we recycle the inode. This ensures that xfs_iunpin will never use the linux inode after it is being freed, and any lookup on an inode on the reclaim list will wait until it is safe to attach a new linux inode to the xfs inode.

The enablement of 64k pages on pseries platforms exposed a bug in the RTAS mechanism for updating firmware. RTAS assumes 4k for flash block and list sizes, and use of any other sizes results in a failure, even though PAPR does not specify any such requirement. This patch changes the rtas_flash module to force the use of 4k memory block and list sizes when preparing and sending a firmware image to RTAS. The rtas_flash function now uses a slab cache of 4k blocks with 4k alignment, rather than get_zeroed_page(), to allocate the memory for the flash blocks and lists. The 4k alignment requirement is specified in PAPR. Signed-off-by:
