Input: elantech - fix touchpad initialization on Gigabyte U2442

2014-06-07T17:28:20Z

commit 36189cc3cd57ab0f1cd75241f93fe01de928ac06 upstream. The hw_version 3 Elantech touchpad on the Gigabyte U2442 does not accept 0x0b as initialization value for r10, this stand-alone version of the driver: http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2 Uses 0x03 which does work, so this means not setting bit 3 of r10 which sets: "Enable Real H/W Resolution In Absolute mode" Which will result in half the x and y resolution we get with that bit set, so simply not setting it everywhere is not a solution. We've been unable to find a way to identify touchpads where setting the bit will fail, so this patch uses a dmi based blacklist for this. https://bugzilla.kernel.org/show_bug.cgi?id=61151 Reported-by: Philipp Wolfer Tested-by: Philipp Wolfer Signed-off-by: Hans de Goede Signed-off-by: Dmitry Torokhov Signed-off-by: Greg Kroah-Hartman

ARM: common: edma: Fix xbar mapping

2014-06-07T17:28:17Z

commit cf7eb979116c2568e8bc3b6a7269c7a359864ace upstream. This is another great example of trainwreck engineering: commit 2646a0e529 (ARM: edma: Add EDMA crossbar event mux support) added support for using EDMA on peripherals which have no direct EDMA event mapping. The code compiles and does not explode in your face, but that's it. 1) Reading an u16 array from an u32 device tree array simply does not work. Even if the function is named "edma_of_read_u32_to_s16_array". It merily calls of_property_read_u16_array. So the resulting 16bit array will have every other entry = 0. 2) The DT entry for the xbar registers related to xbar has length 0x10 instead of the real length: 0xfd0 - 0xf90 = 0x40. Not a real problem as it does not cross a page boundary, but wrong nevertheless. 3) But none of this matters as the mapping never happens: After reading nonsense edma_of_read_u32_to_s16_array() invalidates the first array entry pair, so nobody can ever notice the braindamage by immediate explosion. Seems the QA criteria for this code was solely not to explode when someone adds edma-xbar-event-map entries to the DT. Goal achieved, congratulations! Not really helpful if someone wants to use edma on a device which requires a xbar mapping. Fix the issues by: - annotating the device tree entry with "/bits/ 16" as documented in the of_property_read_u16_array kernel doc - make the size of the xbar register mapping correct - invalidating the end of the array and not the start This convoluted mess wants to be completely rewritten as there is no point to keep the xbar_chan array memory and the iomapping of the xbar regs around forever. Marking the xbar mapped channels as used should be done right there. But that's a different issue and this patch is small enough to make it work and allows a simple backport for stable.

hung_task: check the value of "sysctl_hung_task_timeout_sec"

2014-05-06T14:59:35Z

commit 80df28476505ed4e6701c3448c63c9229a50c655 upstream. As sysctl_hung_task_timeout_sec is unsigned long, when this value is larger then LONG_MAX/HZ, the function schedule_timeout_interruptible in watchdog will return immediately without sleep and with print : schedule_timeout: wrong timeout value ffffffffffffff83 and then the funtion watchdog will call schedule_timeout_interruptible again and again. The screen will be filled with "schedule_timeout: wrong timeout value ffffffffffffff83" This patch does some check and correction in sysctl, to let the function schedule_timeout_interruptible allways get the valid parameter.

spi: efm32: use $vendor,$device scheme for compatible string

commit 12f6dd860cf8bf036c0bec38c00a53da71bcd43a upstream. Wolfram Sang pointed out that "efm32,$device" is non-standard. So use the common scheme and prefix device with "efm32-".

Pull networking fixes from David Miller: "I know this is a bit more than you want to see, and I've told the wireless folks under no uncertain terms that they must severely scale back the extent of the fixes they are submitting this late in the game. Anyways: 1) vmxnet3's netpoll doesn't perform the equivalent of an ISR, which is the correct implementation, like it should. Instead it does something like a NAPI poll operation. This leads to crashes. From Neil Horman and Arnd Bergmann. 2) Segmentation of SKBs requires proper socket orphaning of the fragments, otherwise we might access stale state released by the release callbacks. This is a 5 patch fix, but the initial patches are giving variables and such significantly clearer names such that the actual fix itself at the end looks trivial. From Michael S. Tsirkin. 3) TCP control block release can deadlock if invoked from a timer on an already "owned" socket. Fix from Eric Dumazet. 4) In the bridge multicast code, we must validate that the destination address of general queries is the link local all-nodes multicast address. From Linus Lüssing. 5) The x86 BPF JIT support for negative offsets puts the parameter for the helper function call in the wrong register. Fix from Alexei Starovoitov. 6) The descriptor type used for RTL_GIGA_MAC_VER_17 chips in the r8169 driver is incorrect. Fix from Hayes Wang. 7) The xen-netback driver tests skb_shinfo(skb)->gso_type bits to see if a packet is a GSO frame, but that's not the correct test. It should use skb_is_gso(skb) instead. Fix from Wei Liu. 8) Negative msg->msg_namelen values should generate an error, from Matthew Leach. 9) at86rf230 can deadlock because it takes the same lock from it's ISR and it's hard_start_xmit method, without disabling interrupts in the latter. Fix from Alexander Aring. 10) The FEC driver's restart doesn't perform operations in the correct order, so promiscuous settings can get lost. Fix from Stefan Wahren. 11) Fix SKB leak in SCTP cookie handling, from Daniel Borkmann. 12) Reference count and memory leak fixes in TIPC from Ying Xue and Erik Hugne. 13) Forced eviction in inet_frag_evictor() must strictly make sure all frags are deleted, otherwise module unload (f.e. 6lowpan) can crash. Fix from Florian Westphal. 14) Remove assumptions in AF_UNIX's use of csum_partial() (which it uses as a hash function), which breaks on PowerPC. From Anton Blanchard. The main gist of the issue is that csum_partial() is defined only as a value that, once folded (f.e. via csum_fold()) produces a correct 16-bit checksum. It is legitimate, therefore, for csum_partial() to produce two different 32-bit values over the same data if their respective alignments are different. 15) Fix endiannes bug in MAC address handling of ibmveth driver, also from Anton Blanchard. 16) Error checks for ipv6 exthdrs offload registration are reversed, from Anton Nayshtut. 17) Externally triggered ipv6 addrconf routes should count against the garbage collection threshold. Fix from Sabrina Dubroca. 18) The PCI shutdown handler added to the bnx2 driver can wedge the chip if it was not brought up earlier already, which in particular causes the firmware to shut down the PHY. Fix from Michael Chan. 19) Adjust the sanity WARN_ON_ONCE() in qdisc_list_add() because as currently coded it can and does trigger in legitimate situations. From Eric Dumazet. 20) BNA driver fails to build on ARM because of a too large udelay() call, fix from Ben Hutchings. 21) Fair-Queue qdisc holds locks during GFP_KERNEL allocations, fix from Eric Dumazet. 22) The vlan passthrough ops added in the previous release causes a regression in source MAC address setting of outgoing headers in some circumstances.
