#     mm/mprotect: Fix successful vma_merge() of next in do_mprotect_pkey()
#     
#     If mprotect_fixup() successfully calls vma_merge() and replaces vma and
#     the next vma, then the tmp variable in the do_mprotect_pkey() is not
#     updated to point to the new vma end.  This results in the loop detecting
#     a gap between VMAs that does not exist.
#     
#     Fix the faulty value of tmp by setting it to the end location of the vma
#     iterator at the end of the loop.
