Chris Leech 18fa11efc2 [SCSI] libfc, fcoe: fixes for highmem skb linearize panics 
There are cases outside of our control that may result in a transmit
skb being linearized in dev_queue_xmit.  There are a couple of bugs
in libfc/fcoe that can result in a panic at that point.  This patch
contains two fixes to prevent those panics.

1) use fast cloning instead of shared skbs with dev_queue_xmit

dev_queue_xmit doen't want shared skbuffs being passed in, and
__skb_linearize will BUG if the skb is shared.  FCoE is holding an extra
reference around the call to dev_queue_xmit, so that when it returns an
error code indicating the frame has been dropped it can maintain it's
own backlog and retransmit.  Switch to using fast skb cloning for this
instead.

2) don't append compound pages as > PAGE_SIZE skb fragments

fc_fcp_send_data will append pages from a scatterlist to the nr_frags[]
if the netdev supports it.  But, it's using > PAGE_SIZE compound pages
as a single skb_frag.  In the highmem linearize case that page will be
passed to kmap_atomic to get a mapping to copy out of, but
kmap_atomic will only allow access to the first PAGE_SIZE part.
The memcpy will keep going and cause a page fault once is crosses the
first boundary.

If fc_fcp_send_data uses linear buffers from the start, it calls
kmap_atomic one PAGE_SIZE at a time.  That same logic needs to be
applied when setting up skb_frags.
