[ofa-general] [PATCH] IB/mlx4: Use pgprot_writecombine() for BlueFlame pages

[Roland Dreier]

 > Yes, with this patch, ib_rdma_lat goes down to about 1.2us where without any patch or with Roland's patch it gives about 3.5us 

So the OFED WC patch is work 2.3usec??  Or did you mean 1.2usec
vs. 1.5usec?

In any case it seems my patch is not working on your system.  Do you
have CONFIG_X86_PAT set in your kernel .config?
