commits are listed in priority order, with the first patch fixing an
oops in the EFI capsule code sitting in tip/efi/core, and the rest
being a compiler warning fix, static checker fix, and a couple of
cleanups.

  efivarfs: Make efivarfs_file_ioctl static (2016-05-05 16:52:19 +0100)

----------------------------------------------------------------
 * Fix an oops in the EFI capsule code reported by the 0day bot
   because efi_capsule_pending() was grabbing a mutex in the emergency
   reboot path - Matt Fleming

 * Fix a compiler warning about excessive stack usage in the new efibc
   driver by kmalloc'ing the efivar_entry object - Jeremy Compostella

 * Dan Carpenter reported that it's potentially unsafe to pass the
   address of a pointer to the firmware in efi_capsule_supported().
   Instead we can skip the dynamic allocation entirely and put the
   capsule object on the stack - Matt Fleming

 * Simplify the locking in the efivars code by merging two of
   efivar_init()'s parameters into one - Julia Lawall

 * Cleanup efivarfs_file_ioctl by marking it as static since it has no
   external users - Peter Jones
