* drivers/atm: Use DIV_ROUND_CLOSESTJulia Lawall2009-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* drivers/atm: Correct redundant testJulia Lawall2009-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | str has already been tested. It seems that this test should be on the recently returned value snr. A simplified version of the semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r exists@ local idexpression x; expression E; @@ if (x == NULL || ...) { ... when forall return ...; } ... when != \(x=E\|x--\|x++\|--x\|++x\|x-=E\|x+=E\|x|=E\|x&=E\|&x\) ( *x == NULL | *x != NULL ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

* Replace all DMA_nBIT_MASK macro with DMA_BIT_MASK(n)Yang Hongyang2009-04-13
| | | | | | | | | | | | | | | | 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.

| * solos: Clean up firmware loading codeDavid Woodhouse2009-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
