Sanjay R Mehta 55ebeb4e86 ntb: point to right memory window index 
[ Upstream commit ae89339b08 ]

second parameter of ntb_peer_mw_get_addr is pointing to wrong memory
window index by passing "peer gidx" instead of "local gidx".

For ex, "local gidx" value is '0' and "peer gidx" value is '1', then

on peer side ntb_mw_set_trans() api is used as below with gidx pointing to
local side gidx which is '0', so memroy window '0' is chosen and XLAT '0'
will be programmed by peer side.

    ntb_mw_set_trans(perf->ntb, peer->pidx, peer->gidx, peer->inbuf_xlat,
                    peer->inbuf_size);

Now, on local side ntb_peer_mw_get_addr() is been used as below with gidx
pointing to "peer gidx" which is '1', so pointing to memory window '1'
instead of memory window '0'.

    ntb_peer_mw_get_addr(perf->ntb,  peer->gidx, &phys_addr,
                        &peer->outbuf_size);

So this patch pass "local gidx" as parameter to ntb_peer_mw_get_addr().

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
