* [PATCH 12/15] drivers/atm: Use DIV_ROUND_CLOSEST
From: Julia Lawall @ 2009-08-02 8:48 UTC (permalink / raw)
To: chas, linux-atm-general, netdev, linux-kernel, kernel-janitors
From: Julia Lawall <julia@diku.dk>
The kernel.h macro DIV_ROUND_CLOSEST performs the computation (x + d/2)/d
but is perhaps more readable.
The semantic patch that makes this change is as follows:

* [PATCH] netxen: fix coherent dma mask setting
From: Dhananjay Phadke @ 2009-08-02 7:36 UTC (permalink / raw)
To: davem; +Cc: netdev, Dhananjay Phadke
Change default dma mask for NX3031 to 39 bit with ability
to update it to 64-bit (if firmware indicates support). Old
code was restricting it under 4GB (32-bit), sometimes causing
failure to allocate descriptor rings on heavily populated
system. NX2031 based NICs will still get 32-bit coherent mask.
