The comparison of mode >= 0 is redundant as mode is a u32 and this

Convert the kmap and kmap_atomic uses to the sg_map function. We now
store the flags for the kmap instead of a boolean to indicate
atomicitiy. We also propogate a possible kmap error down and create
a new ISCSI_TCP_INTERNAL_ERR error type for this.

The get_page in this area looks *highly* suspect due to there being no
corresponding put_page. However, I've left that as is to avoid breaking
things.
I've also removed the KMAP_ATOMIC_ARGS check as it appears to be dead

Hi Everyone,
As part of my effort to enable P2P DMA transactions with PCI cards,
we've identified the need to be able to safely put IO memory into
scatterlists (and eventually other spots). This probably involves a
conversion from struct page to pfn_t but that migration is a ways off
and those dec
We use the sg_map helper but it's slightly more complicated
as we only check for the error when the mapping actually gets used.
Such that if the mapping failed but wasn't needed then no
error occurs.

This conversion is a bit complicated. We modiy the read_fifo,
write_fifo and copy_page functions to take a scatterlist instead of a
page. Thus we can use sg_map instead of kmap_atomic. There's a bit of
accounting that needed to be done for the offset for this to work.

Fairly straightforward conversions in all spots. In a couple of cases
any error gets propogated up should sg_map fail. In other
cases a warning is issued if the kmap fails seeing there's no

This patch introduces functions which kmap the pages inside an sgl. Two
variants are provided: one if an offset is required and one if the
offset is zero. These functions replace a common pattern of
