2013-10-15iio:kfifo: Protect against concurrent access from userspaceLars-Peter Clausen
It is possible for userspace to concurrently access the buffer from multiple threads or processes. To avoid corruption of the internal state of the buffer we need to add proper locking. It is possible for multiple processes to try to read from the buffer concurrently and it is also possible that one process causes a buffer re-allocation while a different process still access the buffer. Both can be fixed by protecting the calls to kfifo_to_user() and kfifo_alloc() by the same mutex. In iio_read_first_n_kfifo() we also use kfifo_recsize() instead of the buffers bytes_per_datum to avoid a race that can happen if bytes_per_datum has been changed, but the buffer has not been reallocated yet. Note that all access to the buffer from within the kernel is already properly synchronized, so there is no need for extra locking in iio_store_to_kfifo().

exynos_report_trigger() The commit 4de0bdaa9677d11406c9becb70c60887c957e1f0 ("thermal: exynos: Add support for instance based register/unregister") broke check for presence of therm_dev at global thermal zone in exynos_report_trigger(). The resulting wrong test prevents thermal_zone_device_update() call, which calls handlers for situation when trip points are passed. Such behavior prevents thermal driver from proper reaction (when TMU interrupt is raised) in a situation when overheating is detected at TMU hardware. It turns out, that after exynos thermal subsystem redesign (at v3.12) this check is not needed, since it is not possible to register thermal zone without valid thermal device.

2013-10-15libahci: fix turning on LEDs in ahci_start_port()Lukasz Dorau
If EM Transmit bit is busy during init ata_msleep() is called. It is wrong - msleep() should be used instead of ata_msleep(), because if EM Transmit bit is busy for one port, it will be busy for all other ports too, so using ata_msleep() causes wasting tries for another ports. The most common scenario looks like that now (six ports try to transmit a LED meaasege): - port #0 tries for the 1st time and succeeds - ports #1-5 try for the 1st time and sleeps - port #1 tries for the 2nd time and succeeds - ports #2-5 try for the 2nd time and sleeps - port #2 tries for the 3rd time and succeeds - ports #3-5 try for the 3rd time and sleeps - port #3 tries for the 4th time and succeeds - ports #4-5 try for the 4th time and sleeps - port #4 tries for the 5th time and succeeds - port #5 tries for the 5th time and sleeps At this moment port #5 wasted all its five tries and failed to initialize. Because there are only 5 (EM_MAX_RETRY) tries available usually only five ports succeed to initialize. The sixth port and next ones usually will fail. If msleep() is used instead of ata_msleep() the first port succeeds to initialize in the first try and next ones usually succeed to initialize in the second try. tj: updated comment Signed-off-by: Lukasz Dorau <lukasz.dorau@intel.com> Signed-off-by: Tejun Heo <tj@kernel.org>

2013-10-15KVM: Enable pvspinlock after jump_label_init() to avoid VM hangRaghavendra K T
We use jump label to enable pv-spinlock. With the changes in (442e0973e927 Merge branch 'x86/jumplabel'), the jump label behaviour has changed that would result in eventual hang of the VM since we would end up in a situation where slow path locks would halt the vcpus but we will not be able to wakeup the vcpu by lock releaser using unlock kick. Similar problem in Xen and more detailed description is available in a945928ea270 (xen: Do not enable spinlocks before jump_label_init() has executed) This patch splits kvm_spinlock_init to separate jump label changes with pvops patching and also make jump label enabling after jump_label_init().
