Hi Doug,
These patches adds native support to NOIO allocations during
create QP for IPoIB.
In contrast to the commit 09b93088d750 ("IB: Add a QP creation flag
to use GFP_NOIO allocations"), which added specific QP create flag,
this series uses standard memalloc_noio_* calls to mark GFP_NOIO
for all allocations paths below.
This change allows to all drivers benefit from this facitlity
and not only mlx4 and qib. As a nice outcome, there is a lot
simplification in the mlx4 and qib drivers by removing need to
carry GFP flags.
Thanks
