      Drivers: thermal: remove __dev* attributes. · 4eab7a9e
      Greg Kroah-Hartman authored
      CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
      markings need to be removed.
      
      This change removes the use of __devinit, __devexit_p, __devinitdata,
      and __devexit from these drivers.
      
      Based on patches originally written by Bill Pemberton, but redone by me
      in order to handle some of the coding style issues better, by hand.

      leds: leds-gpio: set devm_gpio_request_one() flags param correctly · 2d7c22f6
      Javier Martinez Canillas authored
      commit a99d76f9 leds: leds-gpio: use gpio_request_one
      
      changed the leds-gpio driver to use gpio_request_one() instead
      of gpio_request() + gpio_direction_output()
      
      Unfortunately, it also made a semantic change that breaks the
      leds-gpio driver.
      
      The gpio_request_one() flags parameter was set to:
      
      GPIOF_DIR_OUT | (led_dat->active_low ^ state)
      
      Since GPIOF_DIR_OUT is 0, the final flags value will just be the
      XOR'ed value of led_dat->active_low and state.
      
      This value were used to distinguish between HIGH/LOW output initial
      level and call gpio_direction_output() accordingly.
      
      With this new semantic gpio_request_one() will take the flags value
      of 1 as a configuration of input direction (GPIOF_DIR_IN) and will
      call gpio_direction_input() instead of gpio_direction_output().
      
      int gpio_request_one(unsigned gpio, unsigned long flags, const char *label)
      {
      ..
      	if (flags & GPIOF_DIR_IN)
      		err = gpio_direction_input(gpio);
      	else
      		err = gpio_direction_output(gpio,
      				(flags & GPIOF_INIT_HIGH) ? 1 : 0);
      ..
      }
      
      The right semantic is to evaluate led_dat->active_low ^ state and
      set the output initial level explicitly.

      Sasha was fuzzing with trinity and reported the following problem:

          handle_pte_fault+0x465/0x6a0
      
      This was triggered by a different version of automatic NUMA balancing
      but in theory the current version is vunerable to the same problem.
      
      do_numa_page
        -> numa_migrate_prep
          -> mpol_misplaced
            -> get_vma_policy
              -> shmem_get_policy
      
      It's very unlikely this will happen as shared pages are not marked
      pte_numa -- see the page_mapcount() check in change_pte_range() -- but
      it is possible.
      
      To address this, this patch restores sp->lock as originally implemented
      by Kosaki Motohiro.  In the path where get_vma_policy() is called, it
      should not be calling sp_alloc() so it is not necessary to treat the PTL
      specially.

      tmpfs mempolicy: fix /proc/mounts corrupting memory · f2a07f40
      Hugh Dickins authored
      Recently I suggested using "mount -o remount,mpol=local /tmp" in NUMA
      mempolicy testing.  Very nasty.  Reading /proc/mounts, /proc/pid/mounts
      or /proc/pid/mountinfo may then corrupt one bit of kernel memory, often
      in a page table (causing "Bad swap" or "Bad page map" warning or "Bad
      pagetable" oops), sometimes in a vm_area_struct or rbnode or somewhere
      worse.  "mpol=prefer" and "mpol=prefer:Node" are equally toxic.
      
      Recent NUMA enhancements are not to blame: this dates back to 2.6.35,
      when commit e17f74af "mempolicy: don't call mpol_set_nodemask() when
      no_context" skipped mpol_parse_str()'s call to mpol_set_nodemask(),
      which used to initialize v.preferred_node, or set MPOL_F_LOCAL in flags.
      With slab poisoning, you can then rely on mpol_to_str() to set the bit
      for node 0x6b6b, probably in the next page above the caller's stack.
      
      mpol_parse_str() is only called from shmem_parse_options(): no_context
      is always true, so call it unused for now, and remove !no_context code.
      Set v.nodes or v.preferred_node or MPOL_F_LOCAL as mpol_to_str() might
      expect.  Then mpol_to_str() can ignore its no_context argument also,
      the mpol being appropriately initialized whether contextualized or not.
      Rename its no_context unused too, and let subsequent patch remove them
      (that's not needed for stable backporting, which would involve rejects).
      
      I don't understand why MPOL_LOCAL is described as a pseudo-policy:
      it's a reasonable policy which suffers from a confusing implementation
      in terms of MPOL_PREFERRED with MPOL_F_LOCAL.  I believe this would be
      much more robust if MPOL_LOCAL were recognized in switch statements
      throughout, MPOL_F_LOCAL deleted, and MPOL_PREFERRED use the (possibly
      empty) nodes mask like everyone else, instead of its preferred_node
      variant (I presume an optimization from the days before MPOL_LOCAL).
      But that would take me too long to get right and fully tested.

      epoll: prevent missed events on EPOLL_CTL_MOD · 128dd175
      Eric Wong authored
      EPOLL_CTL_MOD sets the interest mask before calling f_op->poll() to
      ensure events are not missed.  Since the modifications to the interest
      mask are not protected by the same lock as ep_poll_callback, we need to
      ensure the change is visible to other CPUs calling ep_poll_callback.
      
      We also need to ensure f_op->poll() has an up-to-date view of past
      events which occured before we modified the interest mask.  So this
      barrier also pairs with the barrier in wq_has_sleeper().
      
      This should guarantee either ep_poll_callback or f_op->poll() (or both)
      will notice the readiness of a recently-ready/modified item.
