#     powerpc/pkeys: Copy pkey-tracking-information at fork()
#     
#     At fork(), the pkey tracking information is not copied over to the
#     mm_struct of the child. This can cause the child to erroneously
#     allocate keys that were already allocated. Any allocated execute-only
#     key is lost as well.
#     
#     Add code; called by dup_mmap(), to copy the pkey state from parent to
#     child explicitly.
#     
#     This problem was originally found by Dave Hansen on x86, which turns
#     out to be a problem on powerpc as well.
#
