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.

The argument structs are used in arrays for G_TOPOLOGY IOCTL. The arguments themselves do not need to be aligned to a power of two, but aligning them up to the largest basic type alignment (u64) on common ABIs is a good thing to do. The patch changes the size of the reserved fields to 5 or 6 u32's and aligns the size of the struct to 8 bytes so we do no longer depend on the compiler to perform the alignment. While at it, add __attribute__ ((packed)) to these structs as well. Signed-off-by:

The 5 volt detect functionality broke in 3.14: the code reads IO register 0x70 again after it has already been cleared. Instead it should use the cached irq_reg_0x70 value and the io_write to 0x71 to clear 0x70 can be dropped since this has already been done. Signed-off-by:

Each function range is quite narrow and especially for connectors this will pose a problem. Increase the function ranges while we still can and move the connector range to the end so that range is practically limitless. [mchehab@osg.samsung.com: Rebased to apply at Linus tree] Signed-off-by:

changeset 70433a15 ("media: videobuf2: Refactor vb2_fileio_data and vb2_thread") broke videobuf2-dvb. The root cause is that, instead of calling threadio->fnc() for all types of events except for VB2_BUF_STATE_ERROR, it was calling it only for VB2_BUF_STATE_DONE. With that, the DVB thread were never called. Cc: stable@vger.kernel.org # Kernel >= 4.3 Signed-off-by:

The vb2_thread implementation was made generic and was moved from videobuf2-v4l2.c to videobuf2-core.c in commit af3bac1a. Unfortunately that clearly was never tested since it broke read() causing NULL address references. The root cause was confused handling of vb2_buffer vs v4l2_buffer (the pb pointer in various core functions). The v4l2_buffer no longer exists after moving the code into the core and it is no longer needed. However, the vb2_thread code passed a pointer to a vb2_buffer to the core functions were a v4l2_buffer pointer was expected and vb2_thread expected that the vb2_buffer fields would be filled in correctly. This is obviously wrong since v4l2_buffer != vb2_buffer. Note that the pb pointer is a void pointer, so no type-checking took place. This patch fixes this problem: 1) allow pb to be NULL for vb2_core_(d)qbuf. The vb2_thread code will use a NULL pointer here since they don't care about v4l2_buffer anyway. 2) let vb2_core_dqbuf pass back the index of the received buffer. This is all vb2_thread needs: this index is the index into the q->bufs array and vb2_thread just gets the vb2_buffer from there. 3) the fileio->b pointer (that originally contained a v4l2_buffer) is removed altogether since it is no longer needed. Tested with vivid and the cobalt driver. Cc: stable@vger.kernel.org # Kernel >= 4.3 Signed-off-by:

The tda1004x was updating the properties cache before locking. If the device is not locked, the data at the registers are just random values with no real meaning. This caused the driver to fail with libdvbv5, as such library calls GET_PROPERTY from time to time, in order to return the DVB stats.

This is a partial revert of commit ed8d1cf0 ("[media] Export I2C module alias information in missing drivers") that exported the module aliases for the I2C drivers that were missing to make autoload to work. But there is a bug report [0] that auto load of the ir-kbd-i2c driver cause the Hauppauge HD-PVR driver to not behave correctly. This is a hdpvr latent bug that was just exposed by ir-kbd-i2c module autoloading working and will also happen if the I2C driver is built-in or a user calls modprobe to load the module and register the driver. But there is a regression experimented by users so until the real bug is fixed, let's not export the module alias for the ir-kbd-i2c driver even when this just masks the actual issue.

The Media Control framework now requires entities to be registered with the media device before creating links so commit c7621b30 ("[media] v4l: vsp1: separate links creation from entities init") separated link creation from entities init. But unfortunately that patch introduced a regression since wrong links were created causing a boot failure on Renesas boards. This patch fixes the boot issue and also the media graph was compared by Geert Uytterhoeven to make sure that the driver changes required by the Media Control framework next generation did not affect the graph.

Pull SMB3 fixes from Steve French: "A collection of CIFS/SMB3 fixes. It includes a couple bug fixes, a few for improved debugging of cifs.ko and some improvements to the way cifs does key generation. I do have some additional bug fixes I expect in the next week or two (to address a problem found by xfstest, and some fixes for SMB3.11 dialect, and a couple patches that just came in yesterday that I am reviewing)" * 'for-next' of git://git.samba.org/sfrench/cifs-2.6: cifs_dbg() outputs an uninitialized buffer in cifs_readdir() cifs: fix race between call_async() and reconnect() Prepare for encryption support (first part). Add decryption and encryption key generation. Thanks to Metze for helping with this. cifs: Allow using O_DIRECT with cache=loose cifs: Make echo interval tunable cifs: Check uniqueid for SMB2+ and return -ESTALE if necessary Print IP address of unresponsive server cifs: Ratelimit kernel log messages

Like the Yoga 900 models the Lenovo Yoga 700 does not have a hw rfkill switch, and trying to read the hw rfkill switch through the ideapad module causes it to always reported blocking breaking wifi. This commit adds the Lenovo Yoga 700 to the no_hw_rfkill dmi list, fixing the wifi breakage.

If we detect that there is nothing to do just set the flag and do not check if it was already set before. Races really do not matter. If the flag is set by any code then the shepherd will start dealing with the situation and reenable the vmstat workers when necessary again. Since commit 0eb77e98 ("vmstat: make vmstat_updater deferrable again and shut down on idle") quiet_vmstat might update cpu_stat_off and mark a particular cpu to be handled by vmstat_shepherd. This might trigger a VM_BUG_ON in vmstat_update because the work item might have been sleeping during the idle period and see the cpu_stat_off updated after the wake up. The VM_BUG_ON is therefore misleading and no more appropriate. Moreover it doesn't really suite any protection from real bugs because vmstat_shepherd will simply reschedule the vmstat_work anytime it sees a particular cpu set or vmstat_update would do the same from the worker context directly. Even when the two would race the result wouldn't be incorrect as the counters update is fully idempotent. Reported-by:

Add dummy.o to the targets list, and fill targets automatically from $(vmlinuzobjs) to avoid having to maintain two lists. When building with XZ compression copy ashldi3.c to the build directory to use a different object file for the kernel and zboot. Without this the same object file need to be build with different flags which cause a rebuild at every run. Signed-off-by:
