That pull request contains just local commits, so it's safe to be pulled
in respect of this issue.  The only concern raised on it is from Geert
Uytterhoeven over a bit of missing documentation - basically:

 5) void update_mmu_cache(struct vm_area_struct *vma,
-                        unsigned long address, pte_t pte)
+                        unsigned long address, pte_t *ptep)

        At the end of every page fault, this routine is invoked to
        tell the architecture specific code that a translation
-       described by "pte" now exists at virtual address "address"
-       for address space "vma->vm_mm", in the software page tables.
+       now exists at virtual address "address" for address space
+       "vma->vm_mm", in the software page tables.

the complaint is that 'ptep' is not documented.  "ptep is a pointer to
the pte" wouldn't (at least to me) provide any additional information
to the reader.

I hope that the PXA situation does get straightened out soon, at which
point this will be part of a pull request next week.
