case when Unix Extensions is not enabled and setuids is enabled. This is
necessary to fix the hole in which chown could be allowed for non-root
users in some cases if root mounted, and also to display the mode and uid
properly in some cases.

writev and aio_write to flush properly.

This is Christoph's patch merged with the new nobrl file operations
Signed-off-by: NDave Kleikamp <shaggy@austin.ibm.com>

From: Christoph Hellwig <hch@lst.de>

 - support vectored and async aio ops unconditionally - this is above
   the pagecache and transparent to the fs
 - remove cifs_read_wrapper.  it was only doing silly checks and
   calling generic_file_write in all cases.
 - use do_sync_read/do_sync_write as read/write operations.  They call
   ->readv/->writev which we now always implemente.
 - add the filemap_fdatawrite calls to writev/aio_write which were
   missing previously compared to plain write.  no idea what the point
   behind them is, but let's be consistent at least..

unaligned structures coming in off the wire

gcc on arm processors generates very odd code with pragma pack specified -
although it does pack the structures in some sense - it does not allow you
to access unaligned elements in nested structures at the right offset as other
architectures do.  Oddly enough though, specifying the structures as packed
the long way - one by one with the packed attribute does work.  Rather than
fighting over whether this is a gcc bug or some obscure side effect
of pragma pack, it is easier to do what most (all but 96 other places in
the kernel) do - and replace pragma pack with dozens of attribute(packed)
structure qualifiers.  Much more verbose ... but at least it works.
