is_extcon_changed should only check the idx-th bit of new, not the entirety of new when setting attached. This fixes extcon sending notifications that a cable was inserted when it gets removed while another cable is still connected. Cc: stable@vger.kernel.org Signed-off-by:

The pci device ids listed in the thunderbolt driver are to restrictive, which prevents the driver from being loaded on recent Apple MacBooks using a thunderbolt 2 controller. In particular this prevented any hot-plugging functionality for thunderbolt based ethernet dongles (i.e. Apples thunderbolt gigabit ethernet broadcom tg3 based dongle Model A1433 EMC 2590). Changing the subvendor and subdevice to PCI_ANY_ID the thunderbolt driver loads and binds to the pci device 07:00.0 System peripheral: Intel Corporation Device 156c which is the thunderbolt 2 controller on the MacBookPro12,1. Successfully tested on MacBookPro12,1. With the patch the thunderbolt module gets now loaded on boot. And it provides hot-plugging support both for a cold-plugged and a warm-plugged ethernet dongle.

Commit 505a666e ("writeback: plug writeback in wb_writeback() and writeback_inodes_wb()") has us holding a plug during writeback_sb_inodes, which increases the merge rate when relatively contiguous small files are written by the filesystem. It helps both on flash and spindles. For an fs_mark workload creating 4K files in parallel across 8 drives, this commit improves performance ~9% more by unplugging before calling cond_resched(). cond_resched() doesn't trigger an implicit unplug, so explicitly getting the IO down to the device before scheduling reduces latencies for anyone waiting on clean pages. It also cuts down on how often we use kblockd to unplug, which means less work bouncing from one workqueue to another. Many more details about how we got here: https://lkml.org/lkml/2015/9/11/570Signed-off-by:

The various definitions of __pfn_to_phys() have been consolidated to use a generic macro in include/asm-generic/memory_model.h. This hit mainline in the form of 012dcef3 "mm: move __phys_to_pfn and __pfn_to_phys to asm/generic/memory_model.h". When the generic macro was implemented the type cast to phys_addr_t was dropped which caused boot regressions on ARM platforms with more than 4GB of memory and LPAE enabled. It was suggested to use PFN_PHYS() defined in include/linux/pfn.h as provides the correct logic and avoids further duplication. Reported-by:

Some of the device files are required to be user accessible for PSM while most should remain accessible only by root. Add a parameter to hfi1_cdev_init which controls if the user should have access to this device which places it in a different class with the appropriate devnode callback. In addition set the devnode call back for the existing class to be a bit more explicit for those permissions. Finally remove the unnecessary null check before class_destroy Tested-by:

Commit 2ee507c4 ("sched: Add function single_task_running to let a task check if it is the only task running on a cpu") referenced the current runqueue with the smp_processor_id. When CONFIG_DEBUG_PREEMPT is enabled, that is only allowed if preemption is disabled or the currrent task is bound to the local cpu (e.g. kernel worker). With commit f7819512 ("kvm: add halt_poll_ns module parameter") KVM calls single_task_running. If CONFIG_DEBUG_PREEMPT is enabled that generates a lot of kernel messages. To avoid adding preemption in that cases, as it would limit the usefulness, we change single_task_running to access directly the cpu local runqueue.

Some string_get_size() calls (e.g.: string_get_size(1, 512, STRING_UNITS_10, ..., ...) string_get_size(15, 64, STRING_UNITS_10, ..., ...) ) result in an infinite loop. The problem is that if size is equal to divisor[units]/blk_size and is smaller than divisor[units] we'll end up with size == 0 when we start doing sf_cap calculations: For string_get_size(1, 512, STRING_UNITS_10, ..., ...) case: ... remainder = do_div(size, divisor[units]); -> size is 0, remainder is 1 remainder *= blk_size; -> remainder is 512 ... size *= blk_size; -> size is still 0 size += remainder / divisor[units]; -> size is still 0 The caller causing the issue is sd_read_capacity(), the problem was noticed on Hyper-V, such weird size was reported by host when scanning collides with device removal. This is probably a separate issue worth fixing, this patch is intended to prevent the library routine from infinite looping. Signed-off-by:
