Load the engine microcode when an interface is brought up, instead of of doing it when the module is loaded. Loosen up tight binding between the driver and the engine microcode version. There is no need for microcode update with T3A boards. Fix the file naming. Do a better job at logging the loading activity. Signed-off-by:

cxgb3 used netdev_priv() and dev->priv for different purposes. In 2.6.23, netdev_priv() == dev->priv, cxgb3 needs a fix. This patch is a partial backport of Dave Miller's changes in the net-2.6.24 git branch. Without this fix, cxgb3 crashes on 2.6.23. Signed-off-by:

A network interface can get ARP packets even when the interface has NOARP specified. In a HiperSockets environment this disturbs receiving systems when packets are sent on the multicast queue. (E.g. TCP/IP on z/VM issues messages reporting invalid data on the HiperSockets interface.) Qeth will no longer send ARP packets on HiperSockets interface when interface has the NOARP attribute.

Exclusive usage of OSA-cards has been introduced. Even though Linux does not make use of it, qeth should be prepared to receive a bad RC for some initialization steps. A meaningful message is now given, if an OSA-device is set online, even though the OSA-adapter is already exclusively used by another host. Signed-off-by:

Online setting of a qeth device may fail for instance because of: - out-of-memory condition when allocating qdio queues - IDX ACTIVATE problem - ... Such a device is still returned in a driver_for_each_device loop processed in qeth_reboot_event(), which calls qeth_clear_qdio_buffers(). Make sure qeth_clear_output_buffer() is called only, if the qdio queues have been successfully allocated during initialization of a qeth device. Signed-off-by:

Problem: A recovery thread must not be active when device is removed. In qeth_remove_device() an interruptible wait operation is used to wait until a qeth recovery thread is finished. If a user really interrupts the ungroup operation of a qeth device while a recovery is running, cio and qeth are out of sync (device already removed from cio, but kept in qeth). A following module unload of qeth results in a kernel OOPS here. Solution: Do not allow interruption of ungroup operation to guarantee finishing of a potentially running qeth recovery thread.

This patch fixes two problems during driver unload. The pci_disable_device() call is before firmware reload, causing reads and writes across PCI bus after disabling device.

The IOC3 driver's UART detection bits used to rely on the the firmware setting the UART pre-divider in a way that's apropriate for the 8250 driver which doesn't currently program this register. This happens to work for the console but not rarely for additional ports. While at it, also program the UART to RS-232 PIO mode; it the UART might have been in mac-serial and/or DMA mode though that hasn't actually been observed in practice. Signed-off-by:

David Gibson authored
For hugepage mappings, the file offset, like the address and size, needs to be aligned to the size of a hugepage. In commit 68589bc3, the check for this was moved into prepare_hugepage_range() along with the address and size checks. But since BenH's rework of the get_unmapped_area() paths leading up to commit 4b1d8929, prepare_hugepage_range() is only called for MAP_FIXED mappings, not for other mappings. This means we're no longer ever checking for an aligned offset - I've confirmed that mmap() will (apparently) succeed with a misaligned offset on both powerpc and i386 at least. This patch restores the check, removing it from prepare_hugepage_range() and putting it back into hugetlbfs_file_mmap(). I'm putting it there, rather than in the get_unmapped_area() path so it only needs to go in one place, than separately in the half-dozen or so arch-specific implementations of hugetlb_get_unmapped_area().

Spotted by taoyue <yue.tao@windriver.com> and Jeremy Katz <jeremy.katz@windriver.com>. collect_signal: sigqueue_free: list_del_init(&first->list); if (!list_empty(&q->list)) { // not taken } q->flags &= ~SIGQUEUE_PREALLOC; __sigqueue_free(first); __sigqueue_free(q); Now, __sigqueue_free() is called twice on the same "struct sigqueue" with the obviously bad implications. In particular, this double free breaks the array_cache->avail logic, so the same sigqueue could be "allocated" twice, and the bug can manifest itself via the "impossible" BUG_ON(!SIGQUEUE_PREALLOC) in sigqueue_free/send_sigqueue. Hopefully this can explain these mysterious bug-reports, see http://marc.info/?t=118766926500003 http://marc.info/?t=118466273000005 Alexey Dobriyan reports this patch makes the difference for the testcase, but nobody has an access to the application which opened the problems originally. Also, this patch removes tasklist lock/unlock, ->siglock is enough.

This shows that a driver's irq handler was running both in hard interrupt and process contexts with irqs enabled. The latter was done during free_irq() call and was possible only with CONFIG_DEBUG_SHIRQ enabled. This was fixed by another patch. But similar problem is possible with request_irq(): any locks taken from irq handler could be vulnerable - especially with soft interrupts. This patch fixes it by disabling local interrupts during handler's run. (It seems, disabling softirqs should be enough, but it needs more checking on possible races or other special cases).

This will avoid a possible fault in ecryptfs_sync_page(). In the function, eCryptfs calls sync_page() method of a lower filesystem without checking its existence. However, there are many filesystems that don't have this method including network filesystems such as NFS, AFS, and so forth. They may fail when an eCryptfs page is waiting for lock. Signed-off-by:

Update various SPI drivers so they properly support - coldplug through "modprobe $(cat /sys/devices/.../modalias)" - hotplug through "modprobe $(MODALIAS)" The basic rule for platform, SPI, and (new style) I2C drivers is just to make sure that modprobing the driver name works. In this case, all the relevant drivers are platform drivers, and this patch either (a) Changes the driver name, if no in-tree code would break; this is simpler and thus preferable in the long term. (b) Adds MODULE_ALIAS directives, when in-tree platforms declare devices using the current driver name; less desirable. Most systems will link SPI controller drivers statically, but there's no point in being needlessly broken. Signed-off-by:

Stop UML crashing when trying to dump a process core on x86_64. This is the minimal fix to stop the crash - more things are broken here, and patches are forthcoming. The immediate thing to do is define ELF_CORE_COPY_REGS and ELF_CORE_COPY_FPREGS. Defining ELF_CORE_COPY_FPREGS allows dump_fpu to go away. It is defined in terms of save_fp_registers, so that needs to be added. Signed-off-by:
