Merge tag 'driver-core-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core and sysfs updates from Greg KH: "Here's the big driver core / sysfs update for 3.15-rc1. Lots of kernfs updates to make it useful for other subsystems, and a few other tiny driver core patches. All have been in linux-next for a while" * tag 'driver-core-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (42 commits) Revert "sysfs, driver-core: remove unused {sysfs|device}_schedule_callback_owner()" kernfs: cache atomic_write_len in kernfs_open_file numa: fix NULL pointer access and memory leak in unregister_one_node() Revert "driver core: synchronize device shutdown" kernfs: fix off by one error. kernfs: remove duplicate dir.c at the top dir x86: align x86 arch with generic CPU modalias handling cpu: add generic support for CPU feature based module autoloading sysfs: create bin_attributes under the requested group driver core: unexport static function create_syslog_header firmware: use power efficient workqueue for unloading and aborting fw load firmware: give a protection when map page failed firmware: google memconsole driver fixes firmware: fix google/gsmi duplicate efivars_sysfs_init() drivers/base: delete non-required instances of include <linux/init.h> kernfs: fix kernfs_node_from_dentry() ACPI / platform: drop redundant ACPI_HANDLE check kernfs: fix hash calculation in kernfs_rename_ns() kernfs: add CONFIG_KERNFS sysfs, kobject: add sysfs wrapper for kernfs_enable_ns() ...
