       - Now we have users for it that aren't running Android it turns out
         that regcache_sync_region() is much more useful to drivers if it's
         exported for use by modules.  Who knew?
       - Make sure we don't divide by zero when doing debugfs dumps of
         rbtrees, not visible up until now because everything was providing at
         least some cache on startup.

      tcm_fc: Do not free tpg structure during wq allocation failure · 06383f10
      Mark Rustad authored
      Avoid freeing a registered tpg structure if an alloc_workqueue call
      fails.  This fixes a bug where the failure was leaking memory associated
      with se_portal_group setup during the original core_tpg_register() call.

      tcm_fc: Add abort flag for gracefully handling exchange timeout · e1c40382
      Mark Rustad authored
      Add abort flag and use it to terminate processing when an exchange
      is timed out or is reset. The abort flag is used in place of the
      transport_generic_free_cmd function call in the reset and timeout
      cases, because calling that function in that context would free
      memory that was in use. The aborted flag allows the lifetime to
      be managed in a more normal way, while truncating the processing.
      
      This change eliminates a source of memory corruption which
      manifested in a variety of ugly ways.

      Make the "word-at-a-time" helper functions more commonly usable · f68e556e
      Linus Torvalds authored
      I have a new optimized x86 "strncpy_from_user()" that will use these
      same helper functions for all the same reasons the name lookup code uses
      them.  This is preparation for that.
      
      This moves them into an architecture-specific header file.  It's
      architecture-specific for two reasons:
      
       - some of the functions are likely to want architecture-specific
         implementations.  Even if the current code happens to be "generic" in
         the sense that it should work on any little-endian machine, it's
         likely that the "multiply by a big constant and shift" implementation
         is less than optimal for an architecture that has a guaranteed fast
         bit count instruction, for example.
      
       - I expect that if architectures like sparc want to start playing
         around with this, we'll need to abstract out a few more details (in
         particular the actual unaligned accesses).  So we're likely to have
         more architecture-specific stuff if non-x86 architectures start using
         this.
      
         (and if it turns out that non-x86 architectures don't start using
         this, then having it in an architecture-specific header is still the
         right thing to do, of course)

      cpuidle: Fix panic in CPU off-lining with no idle driver · ee01e663
      Toshi Kani authored
      Fix a NULL pointer dereference panic in cpuidle_play_dead() during
      CPU off-lining when no cpuidle driver is registered.  A cpuidle
      driver may be registered at boot-time based on CPU type.  This patch
      allows an off-lined CPU to enter HLT-based idle in this condition.
