      block: Fix dev_t minor allocation lifetime · 2da78092
      Keith Busch 提交于
      Releases the dev_t minor when all references are closed to prevent
      another device from acquiring the same major/minor.
      
      Since the partition's release may be invoked from call_rcu's soft-irq
      context, the ext_dev_idr's mutex had to be replaced with a spinlock so
      as not so sleep.

      blk-mq: cleanup after blk_mq_init_rq_map failures · 5676e7b6
      Robert Elliott 提交于
      In blk-mq.c blk_mq_alloc_tag_set, if:
      	set->tags = kmalloc_node()
      succeeds, but one of the blk_mq_init_rq_map() calls fails,
      	goto out_unwind;
      needs to free set->tags so the caller is not obligated
      to do so.  None of the current callers (null_blk,
      virtio_blk, virtio_blk, or the forthcoming scsi-mq)
      do so.
      
      set->tags needs to be set to NULL after doing so,
      so other tag cleanup logic doesn't try to free
      a stale pointer later.  Also set it to NULL
      in blk_mq_free_tag_set.
      
      Tested with error injection on the forthcoming
      scsi-mq + hpsa combination.

      Pull Xtensa updates from Chris Zankel:
       "Xtensa improvements for 3.17:
         - support highmem on cores with aliasing data cache.  Enable highmem
           on kc705 by default
         - simplify addition of new core variants (no need to modify Kconfig /
           Makefiles)
         - improve robustness of unaligned access handler and its interaction
           with window overflow/underflow exception handlers
         - deprecate atomic and spill registers syscalls
         - clean up Kconfig: remove orphan MATH_EMULATION, sort 'select'
           statements
         - wire up renameat2 syscall.
      
        Various fixes:
         - fix address checks in dma_{alloc,free}_coherent (runtime BUG)
         - fix access to THREAD_RA/THREAD_SP/THREAD_DS (debug build breakage)
         - fix TLBTEMP_BASE_2 region handling in fast_second_level_miss
           (runtime unrecoverable exception)
         - fix a6 and a7 handling in fast_syscall_xtensa (runtime userspace
           register clobbering)
         - fix kernel/user jump out of fast_unaligned (potential runtime
           unrecoverabl exception)
         - replace termios IOCTL code definitions with constants (userspace
           build breakage)"

      Pull ARM SoC fixes from Olof Johansson:
       "Here's the weekly batch of fixes from arm-soc.
      
        The delta is a largeish negative delta, due to revert of SMP support
        for Broadcom's STB SoC -- it was accidentally merged before some
        issues had been addressed, so they will make a new attempt for 3.18.
        I didn't see a need for a full revert of the whole platform due to
        this, we're keeping the rest enabled.
      
        The rest is mostly:
      
         - a handful of DT fixes for i.MX (Hummingboard/Cubox-i in particular)
         - some MTD/NAND fixes for OMAP
         - minor DT fixes for shmobile
         - warning fix for UP builds on vexpress/spc
      
        There's also a couple of patches that wires up hwmod on TI's DRA7 SoC
        so it can boot.  Drivers and the rest had landed for 3.17, and it's
        small and isolated so it made sense to pick up now even if it's not a
        bugfix"
