NTB: Fix macro parameter conflict with field name

2016-01-22T00:53:10+00:00

If the parameter given to the macro is replaced throughout the macro as
it is evaluated.  The intent is that the macro parameter should replace
the only the first parameter to container_of().  However, the way the
macro was written, it would also inadvertantly replace a structure field
name.  If a parameter of any other name is given to the macro, it will
fail to compile, if the structure does not contain a field of the same
name.  At worst, it will compile, and hide improper access of an
unintended field in the structure.

Change the macro parameter name, so it does not conflict with the
structure field name.

NTB: Clear property bits in BAR value

2016-01-11T14:51:17+00:00

The lower bits read from a BAR register will contain property bits
that we do not care about. Clear those so that we can use the BAR
values for limit and xlat registers.

NTB: unify translation addresses

2015-11-08T21:11:21+00:00

There is no need for the upstream and downstream addresses to be different
for the NTB configs. Go to using a single set of address. It is still
possible to configure them differently using module parameter override
however.

NTB: Improve index handling in B2B MW workaround

2015-09-07T19:27:12+00:00

Check that b2b_mw_idx is in range of the number of memory windows when
initializing the device.  The workaround is considered to be in effect
only if the device b2b_idx is exactly UINT_MAX, instead of any index
past the last memory window.

Only print B2B MW workaround information in debugfs if the workaround is
in effect.

NTB: Add split BAR output for debugfs stats

2015-07-04T18:09:32+00:00

When split BAR is enabled, the driver needs to dump out the split BAR
registers rather than the original 64bit BAR registers.
