      firmware class: export nowait to userspace · e9045f91
      Johannes Berg authored
      When we use request_firmware_nowait(), userspace may
      not want to answer negatively right away when for
      example it is answering from an initrd only, but
      with request_firmware() it has to in order to not
      delay the kernel boot until the request times out.
      
      This allows userspace to differentiate between the
      two in order to be able to reply negatively to async
      requests only when all filesystems have been mounted
      and have been checked for the requested firmware file.

      lockdep: Add novalidate class for dev->mutex conversion · 1704f47b
      Peter Zijlstra authored
      The conversion of device->sem to device->mutex resulted in lockdep
      warnings. Create a novalidate class for now until the driver folks
      come up with separate classes. That way we have at least the basic
      mutex debugging coverage.
      
      Add a checkpatch error so the usage is reserved for device->mutex.

      drivers/base: Convert dev->sem to mutex · 3142788b
      Thomas Gleixner authored
      The semaphore is semantically a mutex. Convert it to a real mutex and
      fix up a few places where code was relying on semaphore.h to be included
      by device.h, as well as the users of the trylock function, as that value
      is now reversed.

      platform_bus: allow custom extensions to system PM methods · 190e8370
      Kevin Hilman authored
      When runtime PM for platform_bus was added, it allowed for platforms
      to customize the runtime PM methods since they are defined as weak
      symbols.
      
      This patch allows platforms to also extend the system PM methods with
      custom hooks so runtime PM and system PM extensions can be managed
      together by custom platform-specific code.

      Driver core: don't initialize wakeup flags · ffa15659
      Alan Stern authored
      This patch (as1351) removes an unnecessary and unwanted assignment
      from device_initialize().  The wakeup flags are set to 0 along with
      everything else when the device structure is allocated, so we don't
      need to do it again.  Furthermore, the subsystem might already have
      set these flags to their correct values; we don't want to override it.

      This patch fix a potential race condition in the driver_bound() function
      in the file driver/base/dd.c.
      
      The broadcast of the BUS_NOTIFY_BOUND_DRIVER notifier should be done
      after adding the new device to the driver list. Otherwise notifier
      listener will fail if they use functions like usb_find_interface().

      Driver core: Reduce the level of request_firmware() messages · 6f18ff91
      Rafael J. Wysocki authored
      The messages from _request_firmware() informing that firmware is
      being requested or built-in firmware is going to be used are printed
      at KERN_INFO, which produces lots of noise on systems with huge
      numbers of AMD CPUs.  Reduce the level of these messages to
      KERN_DEBUG to get rid of that noise.

      kref: remove kref_set · db1afffa
      NeilBrown authored
      Of the three uses of kref_set in the kernel:
      
       One really should be kref_put as the code is letting go of a
          reference,
       Two really should be kref_init because the kref is being
          initialised.
      
      This suggests that making kref_set available encourages bad code.
      So fix the three uses and remove kref_set completely.

      firmware_class: fix memory leak - free allocated pages · dd336c55
      David Woodhouse authored
      fix memory leak introduced by the patch 6e03a201:
      firmware: speed up request_firmware()
      
      1. vfree won't release pages there were allocated explicitly and mapped
      using vmap. The memory has to be vunmap-ed and the pages needs
      to be freed explicitly
      
      2. page array is moved into the 'struct
      firmware' so that we can free it from release_firmware()
      and not only in fw_dev_release()
      
      The fix doesn't break the firmware load speed.
