Before updates from subsystem trees are merged into the mainline 3.x

* pte_offset_map_lock on 32bit PAE kernels was reading the pmd_t with
* a "*pmdp" dereference done by gcc. Problem is, in certain places
* where pte_offset_map_lock is called, concurrent page faults are
* allowed, if the mmap_sem is hold for reading. An example is mincore
* vs page faults vs MADV_DONTNEED. On the page fault side
* pmd_populate rightfully does a set_64bit, but if we're reading the
* pmd_t with a "*pmdp" on the mincore side, a SMP race can happen
* because gcc will not read the 64bit of the pmd atomically. To fix
* this all places running pmd_offset_map_lock() while holding the
* mmap_sem in read mode, shall read the pmdp pointer using this
* function to know if the pmd is null nor not, and in turn to know if
* they can run pmd_offset_map_lock or pmd_trans_huge or other pmd
* operations.
*
* Without THP if the mmap_sem is hold for reading, the
* pmd can only transition from null to not null while pmd_read_atomic runs.
* So there's no need of literally reading it atomically.
*
* With THP if the mmap_sem is hold for reading, the pmd can become
* THP or null or point to a pte (and in turn become "stable") at any
* time under pmd_read_atomic, so it's mandatory to read it atomically
* with cmpxchg8b.
