+Subject: gpio: fix wrong checking condition for gpio range
+
+From: Haojian Zhuang <haojian.zhuang@linaro.org>
+
+commit ad4e1a7caf937ad395ced585ca85a7d14395dc80 upstream.
+
+If index++ calculates from 0, the checking condition of "while
+(index++)" fails & it doesn't check any more. It doesn't follow
+the loop that used at here.
+
+Replace it by endless loop at here. Then it keeps parsing
+"gpio-ranges" property until it ends.

+Subject: kobject: fix kset_find_obj() race with concurrent last kobject_put()
+
+From: Linus Torvalds <torvalds@linux-foundation.org>
+
+commit a49b7e82cab0f9b41f483359be83f44fbb6b4979 upstream.
+
+Anatol Pomozov identified a race condition that hits module unloading
+and re-loading. To quote Anatol:
+
+ "This is a race codition that exists between kset_find_obj() and
+ kobject_put(). kset_find_obj() might return kobject that has refcount
+ equal to 0 if this kobject is freeing by kobject_put() in other
+ thread.
+
+ Here is timeline for the crash in case if kset_find_obj() searches for
+ an object tht nobody holds and other thread is doing kobject_put() on
+ the same kobject:
+
+ THREAD A (calls kset_find_obj()) THREAD B (calls kobject_put())
+ splin_lock()
+ atomic_dec_return(kobj->kref), counter gets zero here
+ ... starts kobject cleanup ....
+ spin_lock() // WAIT thread A in kobj_kset_leave()
+ iterate over kset->list
+ atomic_inc(kobj->kref) (counter becomes 1)
+ spin_unlock()
+ spin_lock() // taken
+ // it does not know that thread A increased counter so it
+ remove obj from list
+ spin_unlock()
+ vfree(module) // frees module object with containing kobj
+
+ // kobj points to freed memory area!!
+ kobject_put(kobj) // OOPS!!!!
+
+ The race above happens because module.c tries to use kset_find_obj()
+ when somebody unloads module. The module.c code was introduced in
+ commit 6494a93d55fa"
+
+Anatol supplied a patch specific for module.c that worked around the
+problem by simply not using kset_find_obj() at all, but rather than make
+a local band-aid, this just fixes kset_find_obj() to be thread-safe
+using the proper model of refusing the get a new reference if the
+refcount has already dropped to zero.
+
+See examples of this proper refcount handling not only in the kref
+documentation, but in various other equivalent uses of this pattern by
+grepping for atomic_inc_not_zero().
+
+[ Side note: the module race does indicate that module loading and
+ unloading is not properly serialized wrt sysfs information using the
+ module mutex. That may require further thought, but this is the
+ correct fix at the kobject layer regardless. ]

+Subject: vfs: Revert spurious fix to spinning prevention in prune_icache_sb
+
+From: Suleiman Souhlal <suleiman@google.com>
+
+commit 5b55d708335a9e3e4f61f2dadf7511502205ccd1 upstream.
+
+Revert commit 62a3ddef6181 ("vfs: fix spinning prevention in prune_icache_sb").
+
+This commit doesn't look right: since we are looking at the tail of the
+list (sb->s_inode_lru.prev) if we want to skip an inode, we should put
+it back at the head of the list instead of the tail, otherwise we will
+keep spinning on it.
+
+Discovered when investigating why prune_icache_sb came top in perf
+reports of a swapping load.

+Subject: x86-32: Fix possible incomplete TLB invalidate with PAE pagetables
+
+From: Dave Hansen <dave@sr71.net>
+
+commit 1de14c3c5cbc9bb17e9dcc648cda51c0c85d54b9 upstream.
+
+This patch attempts to fix:
+
+ https://bugzilla.kernel.org/show_bug.cgi?id=56461
+
+The symptom is a crash and messages like this:
+
+ chrome: Corrupted page table at address 34a03000
+ *pdpt = 0000000000000000 *pde = 0000000000000000
+ Bad pagetable: 000f [#1] PREEMPT SMP
+
+Ingo guesses this got introduced by commit 611ae8e3f520 ("x86/tlb:
+enable tlb flush range support for x86") since that code started to free
+unused pagetables.
+
+On x86-32 PAE kernels, that new code has the potential to free an entire
+PMD page and will clear one of the four page-directory-pointer-table
+(aka pgd_t entries).
+
+The hardware aggressively "caches" these top-level entries and invlpg
+does not actually affect the CPU's copy. If we clear one we *HAVE* to
+do a full TLB flush, otherwise we might continue using a freed pmd page.
+(note, we do this properly on the population side in pud_populate()).
+
+This patch tracks whenever we clear one of these entries in the 'struct
+mmu_gather', and ensures that we follow up with a full tlb flush.
+
+BTW, I disassembled and checked that:
+
+ if (tlb->fullmm == 0)
+and
+ if (!tlb->fullmm && !tlb->need_flush_all)
+
+generate essentially the same code, so there should be zero impact there
+to the !PAE case.
