commit 37252db6 upstream. Due to post-increment in condition of kmod_loop_msg in __request_module(), the system log can be spammed by much more than 5 instances of the 'runaway loop' message if the number of events triggering it makes the kmod_loop_msg to overflow. Fix that by making sure we never increment it past the threshold. Signed-off-by:

commit 75422745 upstream. We should check if the sector is already initialized before trying to grab the page from page cache. Otherwise when two pages of the same block are written back by two threads each calling from writepage_locked, it can cause deadlock like bellow.

commit bee460be upstream. The min_brightness value of the sabi_config is incorrectly used in brightness calculations. For the config where min_brightness = 1 and max_brightness = 8, the user visible range should be 0 to 7 with hardware being set in the range of 1 to 8. What is actually happening is that the user visible range is 0 to 8 with hardware being set in the range of -1 to 7. This patch fixes the above issue as well as a miscalculation that would occur in the case of min_brightness > 1. Signed-off-by:

commit 08613e46 upstream. The caif code will register its own pernet_operations, and then register a netdevice_notifier. Each time the netdevice_notifier is triggered, it'll do some stuff... including a lookup of its own pernet stuff with net_generic(). If the net_generic() call ever returns NULL, the caif code will BUG(). That doesn't seem *so* unreasonable, I suppose — it does seem like it should never happen. However, it *does* happen. When we clone a network namespace, setup_net() runs through all the pernet_operations one at a time. It gets to loopback before it gets to caif. And loopback_net_init() registers a netdevice... while caif hasn't been initialised. So the caif netdevice notifier triggers, and immediately goes BUG(). We could imagine a complex and overengineered solution to this generic class of problems, but this patch takes the simple approach. It just makes caif_device_notify() *not* go looking for its pernet data structures if the device it's being notified about isn't a caif device in the first place. Signed-off-by:

commit ab2a47bd upstream. Propagate the baremetal git commit "swiotlb: fix wrong panic" (fba99fa3) in the Xen-SWIOTLB version. wherein swiotlb's map_page wrongly calls panic() when it can't find a buffer fit for device's dma mask. It should return an error instead. Devices with an odd dma mask (i.e. under 4G) like b44 network card hit this bug (the system crashes): http://marc.info/?l=linux-kernel&m=129648943830106&w=2 If xen-swiotlb returns an error, b44 driver can use the own bouncing mechanism.

commit 917e3e65 upstream. With Xen changeset 23428 "libxl: Add 'e820_host' option to config file" the E820 as seen from the host can now be passed into the guest. This means that a PV guest can now: - Use the correct PCI I/O gap. Before these patches, Linux guest would boot up and would tell: [ 0.000000] Allocating PCI resources starting at 40000000 (gap: 40000000:c0000000) while in actuality the PCI I/O gap should have been: [ 0.000000] Allocating PCI resources starting at b0000000 (gap: b0000000:4c000000) - The PV domain with PCI devices was limited to 3GB. It now can be booted with 4GB, 8GB, or whatever number you want. The PCI devices will now _not_ conflict with System RAM. Meaning the drivers can load.

commit ac06697c upstream. PHY errors relevant for ANI are always tracked by hardware counters, the bits that allow them to pass through the rx filter are independent of that.

commit e9c10469 upstream. Do the magnitude/phase coeff correction only if the outlier is detected. Updating wrong magnitude/phase coeff factor impacts not only tx gain setting but also leads to poor performance in congested networks.

commit 2394d67e upstream. The new runtime PM code has shown that many webcams suffer from a race condition that may crash them upon resume. Runtime PM is especially prone to show the problem because it retains power to the cameras at all times. However system suspension may also crash the devices and retain power to the devices. The only way to solve this problem without races is in usbcore with the RESET_RESUME quirk. Signed-off-by:
