2009-09-30net: Make setsockopt() optlen be unsigned.David S. Miller
This provides safety against negative optlen at the type level instead of depending upon (sometimes non-trivial) checks against this sprinkled all over the the place, in each and every implementation. Based upon work done by Arjan van de Ven and feedback from Linus Torvalds. Signed-off-by: David S. Miller <davem@davemloft.net>
2009-09-28atm: dereference of he_dev->rbps_virt in he_init_group()Juha Leppanen
The prefix decrement causes a very long loop if pci_pool_alloc() failed in the first iteration. Also I swapped rbps and rbpl arguments. Reported-by: Juha Leppanen <juha_motorsportcom@luukku.com> Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-08-02drivers/atm: Use DIV_ROUND_CLOSESTJulia Lawall
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: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @haskernel@ @@ #include <linux/kernel.h> @depends on haskernel@ expression x,__divisor; @@ - (((x) + ((__divisor) / 2)) / (__divisor)) + DIV_ROUND_CLOSEST(x,__divisor) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

2009-07-27drivers/atm: Correct redundant testJulia Lawall

2009-05-07solos: Show Interleaving details for ADSL2 and 2+Simon Farnsworth
InterleaveRDn and InterleaveRUp only apply to G.dmt. The equivalents for ADSL2 and 2+ are BisRDn and BisRUp. In addition, the INPdown and INPup statuses are useful when trying to track down instability on a line.

This is the second go through of the old DMA_nBIT_MASK macro,and there're not so many of them left,so I put them into one patch.I hope this is the last round. After this the definition of the old DMA_nBIT_MASK macro could be removed.

2009-01-27solos: Clean up firmware loading codeDavid Woodhouse
We no longer try to load firmware while the ATM is up and running. However, this means that we _do_ make init_module() wait for it, and it takes a long time for now (since we're using ultra-conservative code in the FPGA for that too). The inner loop which uses swahb32p() was by Simon Farnsworth. Simon has patches which migrate us to request_firmware_nowait(), for which we'll actually need to take down the ATM devices, do the upgrade, then reregister them.
