[ Upstream commit 9dcb3df4 ] The interrupt controller inside the Wii's Hollywood chip is connected to two masters, the "Broadway" PowerPC and the "Starlet" ARM926, each with their own interrupt status and mask registers. When booting the Wii with mini[1], interrupts from the SD card controller (IRQ 7) are handled by the ARM, because mini provides SD access over IPC. Linux however can't currently use or disable this IPC service, so both sides try to handle IRQ 7 without coordination. Let's instead make sure that all interrupts that are unmasked on the PPC side are masked on the ARM side; this will also make sure that Linux can properly talk to the SD card controller (and potentially other devices). If access to a device through IPC is desired in the future, interrupts from that device should not be handled by Linux directly. [1]: https://github.com/lewurm/miniSigned-off-by:

[ Upstream commit 7a2148df ] The current code decrements the timeout counter i and the end of each loop i is incremented, so the check for timeout will always be false and hence the timeout mechanism is just a dead code path. Potentially, if the RD_READY bit is not set, we could end up in an infinite loop. Fix this so the timeout starts from 1000 and decrements to zero, if at the end of the loop i is zero we have a timeout condition.

Before spare disks recovery completing, system reboot and mdadm thinks it is ok to restart the degraded array by md_ioctl(). Since disks in raid6 is not only_parity(), raid5_run() will abort, when there is no PPL feature or not setting 'start_dirty_degraded' parameter. Therefore, mddev->pers is NULL. But, mddev->raid_disks has been set and it will not be cleared when raid5_run abort. md_ioctl() can execute cmd 'HOT_REMOVE_DISK' to remove a disk by mdadm, which will cause NULL pointer dereference in remove_and_add_spares() finally.

[ Upstream commit 2e3611e9 ] The device can set the exception event bit in one of the response UPIU, for example to notify the need for urgent BKOPs operation. In such a case, the host driver calls ufshcd_exception_event_handler to handle this notification. When trying to check the exception event status (for finding the cause for the exception event), the device may be busy with additional SCSI commands handling and may not respond within the 100ms timeout. To prevent that, we need to block SCSI commands during handling of exception events and allow retransmissions of the query requests, in case of timeout. Signed-off-by:

Such case could happen by just looping btrfs/017 and with some possibility it can hit such double qgroup accounting problem. Fix it by checking the path to determine if we should finish qgroup rescan, other than relying on next loop to exit. Reported-by:

[ Upstream commit 3d3a2e61 ] Currently the code assumes that there's an implied barrier by the sequence of code preceding the wakeup, namely the mutex unlock. As Nikolay pointed out: I think this is wrong (not your code) but the original assumption that the RELEASE semantics provided by mutex_unlock is sufficient. According to memory-barriers.txt: Section 'LOCK ACQUISITION FUNCTIONS' states: (2) RELEASE operation implication: Memory operations issued before the RELEASE will be completed before the RELEASE operation has completed. Memory operations issued after the RELEASE *may* be completed before the RELEASE operation has completed. (I've bolded the may portion) The example given there: As an example, consider the following: *A = a; *B = b; ACQUIRE *C = c; *D = d; RELEASE *E = e; *F = f; The following sequence of events is acceptable: ACQUIRE, {*F,*A}, *E, {*C,*D}, *B, RELEASE So if we assume that *C is modifying the flag which the waitqueue is checking, and *E is the actual wakeup, then those accesses can be re-ordered... IMHO this code should be considered broken... Signed-off-by:

[ Upstream commit 0f22e400 ] Make sure the rx_allocator worker is canceled before running the rx_init routine. rx_init frees and re-allocates all rxb's pages. The rx_allocator worker also allocates pages for the used rxb's. Running rx_init and rx_allocator simultaniously causes a kernel panic. Fix that by canceling the work in rx_init. Signed-off-by:

[ Upstream commit d71f11c0 ] For Nehalem and Westmere, there is only one fixed counter for W-Box. There is no index which is bigger than UNCORE_PMC_IDX_FIXED. It is not correct to use >= to check fixed counter. The code quality issue will bring problem when new counter index is introduced. Signed-off-by:

[ Upstream commit 4749f819 ] There is no index which is bigger than UNCORE_PMC_IDX_FIXED. The only exception is client IMC uncore, which has been specially handled. For generic code, it is not correct to use >= to check fixed counter. The code quality issue will bring problem when a new counter index is introduced. Signed-off-by:

[ Upstream commit d179f99a ] detach_port() fails to call usbip_vhci_driver_close() from its error path after usbip_vhci_detach_device() returns failure, leaking memory allocated in usbip_vhci_driver_open() and holding udev_context and udev references. Fix it to call usbip_vhci_driver_close(). Signed-off-by:
