When resuming from suspend newer Synaptics touchpads do not recover correctly. Analysis of the resume sequence as applied in Linux was compared to that of other operating systems. This indicated that the other OSs were resetting the mouse before attempting to detect it (for all Synaptics touchpads, old and new). Applying this same modification fixes these newer Synaptics touchpads and brings the driver into line with common OS reset behaviour.

Commit ec42d448 broke usbtouchscreen for some eGalax/EETI devices that claim to be HID, but are not. Devices confirmed to be real HID have the class set to HID and the protocol set to 'mouse'. Some have HID class but protocol set to 'none'. Those are not HID and should be driven by usbtouchscreen. Fix the device ignoring macro by adding match for the protocol too.

A pointer to spitzkbd_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

由 Harry Ciao 提交于
When deleting an edac device, we have to wait for its edac_dev.work to be completed before deleting the whole edac_dev structure. Since we have no idea which work in current edac_poller's workqueue is the work we are conerned about, we wait for all work in the edac_poller's workqueue to be proceseed. This is done via flush_cpu_workqueue() which inserts a wq_barrier into the tail of the workqueue and then sleeping on the completion of this wq_barrier. The edac_poller will wake up sleepers when it is found. EDAC core creates only one kernel worker thread, edac_poller, to run the works of all current edac devices. They share the same callback function of edac_device_workq_function(), which would grab the mutex of device_ctls_mutex first before it checks the device. This is exactly where edac_poller and rmmod would have a great chance to deadlock. In below call trace of rmmod > ... > edac_device_del_device > edac_device_workq_teardown > flush_workqueue > flush_cpu_workqueue, device_ctls_mutex would have already been grabbed by edac_device_del_device(). So, on one hand rmmod would sleep on the completion of a wq_barrier, holding device_ctls_mutex; on the other hand edac_poller would be blocked on the same mutex when it's running any one of works of existing edac evices(Note, this edac_dev.work is likely to be totally irrelevant to the one that is being removed right now)and never would have a chance to run the work of above wq_barrier to wake rmmod up. edac_device_workq_teardown() should not be called within the critical region of device_ctls_mutex. Just like is done in edac_pci_del_device() and edac_mc_del_mc(), where edac_pci_workq_teardown() and edac_mc_workq_teardown() are called after related mutex are released. Moreover, an edac_dev.work should check first if it is being removed. If this is the case, then it should bail out immediately. Since not all of existing edac devices are to be removed, this "shutting flag" should be contained to edac device being removed. The current edac_dev.op_state can be used to serve this purpose. The original deadlock problem and the solution have been witnessed and tested on actual hardware. Without the solution, rmmod an edac driver would result in below deadlock: root@localhost:/root> rmmod mv64x60_edac EDAC DEBUG: mv64x60_dma_err_remove() EDAC DEBUG: edac_device_del_device() EDAC DEBUG: find_edac_device_by_dev() (hang for a moment) INFO: task edac-poller:2030 blocked for more than 120 seconds.

acpi_early_init() was changed to over-write the cmdline param, making it really inconvenient to set debug flags at boot-time. Also, This sets the default level to "info", which is what all the ACPI drivers use. So to enable messages from drivers, you only have to supply the "layer" (a.k.a. "component"). For non-"info" ACPI core and ACPI interpreter messages, you have to supply both level and layer masks, as before.

When we read the write-intent-bitmap off the device, we currently read a whole number of pages. When PAGE_SIZE is 4K, this works due to the alignment we enforce on the superblock and bitmap. When PAGE_SIZE is 64K, this case read past the end-of-device which causes an error. When we write the superblock, we ensure to clip the last page to just be the required size. Copy that code into the read path to just read the required number of sectors. Signed-off-by: NNeil Brown <neilb@suse.de> Cc: stable@kernel.org
