Dmitry Safonov cd544fd1dc mremap: don't allow MREMAP_DONTUNMAP on special_mappings and aio 
As kernel expect to see only one of such mappings, any further operations
on the VMA-copy may be unexpected by the kernel.  Maybe it's being on the
safe side, but there doesn't seem to be any expected use-case for this, so
restrict it now.
