2012-09-28ath9k: Fix rx filtering issue for older chipsThomas Wagner
We need to have the promiscuous mode enabled for older chipsets so that the olderchips hardware does not filters out some valid/necessary frames that need to be sent to mac80211. Fix this by enabling promiscus mode for all the chipsets whose macversion <= AR9160 chipsets. This should fix https://bugzilla.kernel.org/show_bug.cgi?id=45591 shafi: made the fix generic by having the frame filtering disabled for chipsets older than AR9280.

If the ExpressKeys on the Intuos5 are touched, they currently result an out-of-prox packet being sent even if the pad is already out of prox. This can cause some confusion in the X driver.

2012-09-28Input: synaptics - adjust threshold for treating position values as negativeSeth Forshee
Commit c039450 (Input: synaptics - handle out of bounds values from the hardware) caused any hardware reported values over 7167 to be treated as a wrapped-around negative value. It turns out that some firmware uses the value 8176 to indicate a finger near the edge of the touchpad whose actual position cannot be determined. This value now gets treated as negative, which can cause pointer jumps and broken edge scrolling on these machines. I only know of one touchpad which reports negative values, and this hardware never reports any value lower than -8 (i.e. 8184). Moving the threshold for treating a value as negative up to 8176 should work fine then for any hardware we currently know about, and since we're dealing with unspecified behavior it's probably the best we can do. The special 8176 value is also likely to result in sudden jumps in position, so let's also clamp this to the maximum specified value for the axis.

2012-09-28iommu/amd: Make sure IOMMU is not considered to translate itselfJoerg Roedel

2012-09-28iommu/amd: Split device table initialization into irq and dma partJoerg Roedel
When the IOMMU is enabled very early (as with irq-remapping) some devices are still in BIOS hand. When dma is blocked early this can cause lots of IO_PAGE_FAULTs. So delay the DMA initialization and do it right before the dma_ops are initialized. To be secure, block all interrupts by default when irq-remapping is enabled in the system. They will be reenabled on demand later. Without blocking interrupts by default devices can issue arbitrary interrupts by sending special DMA packets to the CPU that look like MSI messages. This is especially dangerous when a device is assigned to a KVM guest because the guest can then DoS the host. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>

2012-09-28iommu/amd: Fix wrong assumption in iommu-group specific codeJoerg Roedel
The new IOMMU groups code in the AMD IOMMU driver makes the assumption that there is a pci_dev struct available for all device-ids listed in the IVRS ACPI table. Unfortunatly this assumption is not true and so this code causes a NULL pointer dereference at boot on some systems. Fix it by making sure the given pointer is never NULL when passed to the group specific code. The real fix is larger and will be queued for v3.7.

2012-09-28firewire: addendum to address handler RCU conversionStefan Richter
Follow up on commit c285f6ff6787 "firewire: remove global lock around address handlers, convert to RCU": - address_handler_lock no longer serializes the address handler, only its function to serialize updates to the list of handlers remains. Rename the lock to address_handler_list_lock. - Callers of fw_core_remove_address_handler() must be able to sleep. Comment on this in the API documentation. - The counterpart fw_core_add_address_handler() is by nature something which is used in process context. Replace spin_lock_bh() by spin_lock() in fw_core_add_address_handler() and in fw_core_remove_address_handler(), and document that process context is now required for fw_core_add_address_handler(). - Extend the documentation of fw_address_callback_t.

2012-09-28firewire: remove global lock around address handlers, convert to RCUPeter Hurley
Upper-layer handlers for inbound requests were called with a spinlock held by firewire-core. Calling into upper layers with a lower layer lock held is generally a bad idea. What's more, since commit ea102d0ec475 "firewire: core: convert AR-req handler lock from _irqsave to _bh", a caller of fw_send_request() i.e. initiator of outbound request could no longer do that while having interrupts disabled, if the local node was addressed by that request. In order to make all this more flexible, convert the management of address ranges and handlers from a global lock around readers and writers to RCU (and a remaining global lock for writers). As a minor side effect, handling of inbound requests at different cards and of local requests is now no longer serialized. (There is still per-card serialization of remote requests since firewire-ohci uses a single DMA tasklet for inbound request events.) In other words, address handlers are now called in an RCU read-side critical section instead of from within a spin_lock_bh serialized section. (Changelog rewritten by Stefan R.)
