2013-04-03usb: phy: samsung: convert to devm_ioremap_resource()Sachin Kamat
Use the newly introduced devm_ioremap_resource() instead of devm_request_and_ioremap() which provides more consistent error handling. devm_ioremap_resource() provides its own error messages; so all explicit error messages can be removed from the failure code paths.

2013-04-02PCI: Don't try to disable Bus Master on disconnected PCI devicesKonstantin Khlebnikov
This is a fix for commit 7897e60227 ("PCI: Disable Bus Master unconditionally in pci_device_shutdown()"). Vivek reported that with this commit, kexec failed because none of his SATA disks came up. A ->shutdown() callback might put the device in D3cold, which means config space is no longer available.

2013-04-02Revert "PCI/ACPI: Request _OSC control before scanning PCI root bus"Bjorn Helgaas
This reverts commit 8c33f51df406e1a1f7fa4e9b244845b7ebd61fa6. Conflicts: drivers/acpi/pci_root.c This commit broke some pre-1.1 PCIe devices by leaving them with ASPM enabled. Previously, we had disabled ASPM on these devices because many of them don't implement it correctly (per 149e1637). Requesting _OSC control early means that aspm_disabled may be set before we scan the PCI bus and configure link ASPM state. But the ASPM configuration currently skips the check for pre-PCIe 1.1 devices when aspm_disabled is set, like this: acpi_pci_root_add acpi_pci_osc_support if (flags != base_flags) pcie_no_aspm aspm_disabled = 1 pci_acpi_scan_root ... pcie_aspm_init_link_state pcie_aspm_sanity_check if (!aspm_disabled) /* check for pre-PCIe 1.1 device */ Therefore, setting aspm_disabled early means that we leave ASPM enabled on these pre-PCIe 1.1 devices, which is a regression for some devices. The best fix would be to clean up the ASPM init so we can evaluate _OSC before scanning the bug (that way boot-time and hot-add discovery will work the same), but that requires significant rework. For now, we'll just revert the _OSC change as the lowest-risk fix. Reference: https://bugzilla.kernel.org/show_bug.cgi?id=55211 Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Rafael J.

2013-04-02x86: remove the x32 syscall bitmask from syscall_get_nr()Paul Moore
Commit fca460f95e928bae373daa8295877b6905bc62b8 simplified the x32 implementation by creating a syscall bitmask, equal to 0x40000000, that could be applied to x32 syscalls such that the masked syscall number would be the same as a x86_64 syscall. While that patch was a nice way to simplify the code, it went a bit too far by adding the mask to syscall_get_nr(); returning the masked syscall numbers can cause confusion with callers that expect syscall numbers matching the x32 ABI, e.g. unmasked syscall numbers. This patch fixes this by simply removing the mask from syscall_get_nr() while preserving the other changes from the original commit. While there are several syscall_get_nr() callers in the kernel, most simply check that the syscall number is greater than zero, in this case this patch will have no effect. Of those remaining callers, they appear to be few, seccomp and ftrace, and from my testing of seccomp without this patch the original commit definitely breaks things; the seccomp filter does not correctly filter the syscalls due to the difference in syscall numbers in the BPF filter and the value from syscall_get_nr(). Applying this patch restores the seccomp BPF filter functionality on x32. I've tested this patch with the seccomp BPF filters as well as ftrace and everything looks reasonable to me; needless to say general usage seemed fine as well.

2013-04-03drm: correctly restore mappings if drm_open failsIlija Hadzic
If first drm_open fails, the error-handling path will incorrectly restore inode's mapping to NULL. This can cause the crash later on. Fix by separately storing away mapping pointers that drm_open can touch and restore each from its own respective variable if the call fails.

2013-04-02VSOCK: Handle changes to the VMCI context ID.Reilly Grant
The VMCI context ID of a virtual machine may change at any time. There is a VMCI event which signals this but datagrams may be processed before this is handled. It is therefore necessary to be flexible about the destination context ID of any datagrams received. (It can be assumed to be correct because it is provided by the hypervisor.) The context ID on existing sockets should be updated to reflect how the hypervisor is currently referring to the system.

2013-04-02net IPv6 : Fix broken IPv6 routing table after loopback down-upBalakumaran Kannan
IPv6 Routing table becomes broken once we do ifdown, ifup of the loopback(lo) interface. After down-up, routes of other interface's IPv6 addresses through 'lo' are lost. IPv6 addresses assigned to all interfaces are routed through 'lo' for internal communication. Once 'lo' is down, those routing entries are removed from routing table. But those removed entries are not being re-created properly when 'lo' is brought up. So IPv6 addresses of other interfaces becomes unreachable from the same machine. Also this breaks communication with other machines because of NDISC packet processing failure. This patch fixes this issue by reading all interface's IPv6 addresses and adding them to IPv6 routing table while bringing up 'lo'. ==Testing== Before applying the patch: $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo 2000::20/128 :: Un 0 1 0 lo fe80::xxxx:xxxx:xxxx:xxxx/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ sudo ifdown lo $ sudo ifup lo $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ After applying the patch: $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo 2000::20/128 :: Un 0 1 0 lo fe80::xxxx:xxxx:xxxx:xxxx/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ sudo ifdown lo $ sudo ifup lo $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo 2000::20/128 :: Un 0 1 0 lo fe80::xxxx:xxxx:xxxx:xxxx/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ Signed-off-by: Balakumaran Kannan <Balakumaran.Kannan@ap.sony.com> Signed-off-by: Maruthi Thotad <Maruthi.Thotad@ap.sony.com> Signed-off-by: David S.

2013-04-02cbq: incorrect processing of high limitsVasily Averin
currently cbq works incorrectly for limits > 10% real link bandwidth, and practically does not work for limits > 50% real link bandwidth.

2013-04-02ACPI / I2C: Use parent's ACPI_HANDLE() in acpi_i2c_register_devices()Rafael J. Wysocki
The ACPI handle of struct i2c_adapter's dev member should not be set, because this causes that struct i2c_adapter to be associated with the ACPI device node corresponding to its parent as the second "physical_device", which is incorrect (this happens during the registration of struct i2c_adapter). Consequently, acpi_i2c_register_devices() should use the ACPI handle of the parent of the struct i2c_adapter it is called for rather than the struct i2c_adapter's ACPI handle (which should be NULL). Make that happen and modify the i2c-designware-platdrv driver, which currently is the only driver for ACPI-enumerated I2C controller chips, not to set the ACPI handle for the struct i2c_adapter it creates.

This patch let ELD debug message show 'pin_eld->monitor_present' which reflects the real pin response to verb GET_PIN_SENSE. 'eld->monitor_present' should not be used here because 'eld' is a temp structure now and so its "monitor_present" is not set.

In function snd_hdmi_get_eld(), the variable 'ret' should be initialized to 0. Otherwise it will be returned uninitialized as non-zero after ELD info is got successfully. Thus hdmi_present_sense() will always assume ELD info is invalid by mistake, and /proc file system cannot show the proper ELD info.

Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following build warning when CONFIG_PM_SLEEP is not selected.

2013-04-02usb: musb: implement (un)map_urb_for_dma hooksRuslan Bilovol
MUSB controller cannot work in DMA mode with misaligned buffers, switching in PIO mode. HCD core has hooks that allow to override the default DMA mapping and unmapping routines for host controllers that have special DMA requirements, such as alignment constraints. It is observed that work in PIO mode is slow and it's better to align buffers properly before passing them to MUSB This increased throughput 80->120 MBits/s over musb@omap4 with USB Gigabit Ethernet adapter attached.

2013-04-02usb: gadget/uvc: Port UVC webcam gadget to use videobuf2 frameworkBhupesh Sharma
This patch reworks the videobuffer management logic present in the UVC webcam gadget and ports it to use the "more apt" videobuf2 framework for video buffer management. To support routing video data captured from a real V4L2 video capture device with a "zero copy" operation on videobuffers (as they pass from the V4L2 domain to UVC domain via a user-space application), we need to support USER_PTR IO method at the UVC gadget side. So the V4L2 capture device driver can still continue to use MMAP IO method and now the user-space application can just pass a pointer to the video buffers being dequeued from the V4L2 device side while queueing them at the UVC gadget end. This ensures that we have a "zero-copy" design as the videobuffers pass from the V4L2 capture device to the UVC gadget. Note that there will still be a need to apply UVC specific payload headers on top of each UVC payload data, which will still require a copy operation to be performed in the 'encode' routines of the UVC gadget. This patch also addresses one issue found out while porting the UVC gadget to videobuf2 framework: - In case the usb requests queued by the gadget get completed with a status of -ESHUTDOWN (disconnected from host), the queue of videobuf2 should be cancelled to ensure that the application space daemon is not left in a state waiting for a vb2 to be successfully absorbed at the USB side.
