2016-03-10dm thin metadata: don't issue prefetches if a transaction abort has failedJoe Thornber
If a transaction abort has failed then we can no longer use the metadata device. Typically this happens if the superblock is unreadable.

2016-03-10net-next: mediatek: add support for MT7623 ethernetJohn Crispin
Add ethernet support for MediaTek SoCs from the MT7623 family. These have dual GMAC. Depending on the exact version, there might be a built-in Gigabit switch (MT7530). The core does not have the typical DMA ring setup. Instead there is a linked list that we add descriptors to. There is only one linked list that both MACs use together. There is a special field inside the TX descriptors called the VQID. This allows us to assign packets to different internal queues. By using a separate id for each MAC we are able to get deterministic results for BQL. Additionally we need to provide the core with a block of scratch memory that is the same size as the RX ring and data buffer. This is really needed to make the HW datapath work. Although the driver does not support this yet, we still need to assign the memory and tell the core about it for RX to work.

2016-03-10ACPICA / Interpreter: Fix a regression triggered because of wrong Linux ECDT ↵Lv Zheng
support It is reported that the following commit triggers regressions: Linux commit: efaed9be998b5ae0afb7458e057e5f4402b43fa0 ACPICA commit: 31178590dde82368fdb0f6b0e466b6c0add96c57 Subject: ACPICA: Events: Enhance acpi_ev_execute_reg_method() to ensure no _REG evaluations can happen during OS early boot stages This is because that the ECDT support is not corrected in Linux, and Linux requires to execute _REG for ECDT (though this sounds so wrong), we need to ensure acpi_gbl_namespace_initialized is set before ECDT probing in order for _REG to be executed. Since we have to move "acpi_gbl_namespace_initialized = TRUE" to the initialization step happening before ECDT probing, acpi_load_tables() is the best candidate for now. Thus this patch fixes the regression by doing so. But if the ECDT support is fixed, Linux will not execute _REG for ECDT, and ECDT probing will happen before acpi_load_tables(). At that time, we still want to ensure acpi_gbl_namespace_initialized is set after executing acpi_ns_initialize_objects() (under the condition of acpi_gbl_group_module_level_code = FALSE), this patch also moves acpi_ns_initialize_objects() to acpi_load_tables() accordingly. Since acpi_ns_initialize_objects() doesn't seem to be skippable, this patch also removes ACPI_NO_OBJECT_INIT for the one invoked in acpi_load_tables(). And since the default region handlers should always be installed before loading the tables, this patch also removes useless acpi_gbl_group_module_level_code check accordingly.

2016-03-10PCI: Prevent VPD access for buggy devicesBabu Moger

2016-03-10PCI: Sleep rather than busy-wait for VPD access completionBjorn Helgaas
Use usleep_range() instead of udelay() while waiting for a VPD access to complete. This is not a performance path, so no need to hog the CPU. Rationale for usleep_range() parameters: We clear PCI_VPD_ADDR_F for a read (or set it for a write), then wait for the device to change it. For a device that updates PCI_VPD_ADDR between our config write and subsequent config read, we won't sleep at all and can get the device's maximum rate. Sleeping a minimum of 10 usec per 4-byte access limits throughput to about 400Kbytes/second. VPD is small (32K bytes at most), and most devices use only a fraction of that. We back off exponentially up to 1024 usec per iteration. If we reach 1024, we've already waited up to 1008 usec (16 + 32 + ... + 512), so if we miss an update and wait an extra 1024 usec, we can still get about 1/2 of the device's maximum rate.

2016-03-10cpufreq: Move scheduler-related code to the sched directoryRafael J. Wysocki
Create cpufreq.c under kernel/sched/ and move the cpufreq code related to the scheduler to that file and to sched.h. Redefine cpufreq_update_util() as a static inline function to avoid function calls at its call sites in the scheduler code (as suggested by Peter Zijlstra). Also move the definition of struct update_util_data and declaration of cpufreq_set_update_util_data() from include/linux/cpufreq.h to include/linux/sched.h. Signed-off-by: Rafael J.

2016-03-10[media] media-device: map new functions into old types for legacy APIMauro Carvalho Chehab
The legacy media controller userspace API exposes entity types that carry both type and function information. The new API replaces the type with a function. It preserves backward compatibility by defining legacy functions for the existing types and using them in drivers. This works fine, as long as newer entity functions won't be added. Unfortunately, some tools, like media-ctl with --print-dot argument rely on the now legacy MEDIA_ENT_T_V4L2_SUBDEV and MEDIA_ENT_T_DEVNODE numeric ranges to identify what entities will be shown. Also, if the entity doesn't match those ranges, it will ignore the major/minor information on devnodes, and won't be getting the devnode name via udev or sysfs. As we're now adding devices outside the old range, the legacy ioctl needs to map the new entity functions into a type at the old range, or otherwise we'll have a regression. Detected on all released media-ctl versions (e. g. versions <= 1.10). Fix this by deriving the type from the function to emulate the legacy API if the function isn't in the legacy functions range.

2016-03-10EDAC/sb_edac: Fix computation of channel addressLuck, Tony
Large memory Haswell-EX systems with multiple DIMMs per channel were sometimes reporting the wrong DIMM. Found three problems: 1) Debug printouts for socket and channel interleave were not interpreting the register fields correctly. The socket interleave field is a 2^X value (0=1, 1=2, 2=4, 3=8). The channel interleave is X+1 (0=1, 1=2, 2=3. 3=4). 2) Actual use of the socket interleave value didn't interpret as 2^X 3) Conversion of address to channel address was complicated, and wrong.

2016-03-10HID: usbhid: enable NO_INIT_REPORTS quirk for Semico USB Keykoard2Daniel Bristot de Oliveira
The device which identifies itself as a "USB Keykoard" (no typo) with VID:PID 1a2c:0027 does not seem to be handling the reports initialization very well. This results in a "usb_submit_urb(ctrl) failed: -1" message from the kernel when connected, and a delay before its initialization. It can also cause the hang the system. This patch adds the quirk for this device, which causes the delay to disappear. It is named as "USB Keykoard2" because the "USB Keykoard" already exists.
