      ethernet: Remove casts to same type · 64699336
      由 Joe Perches 提交于 
      Adding casts of objects to the same type is unnecessary
and confusing for a human reader.

For example, this cast:

        int y;
        int *p = (int *)&y;

I used the coccinelle script below to find and remove these
unnecessary casts.  I manually removed the conversions this
script produces of casts with __force, __iomem and __user.

@@
type T;
T *p;
@@

-       (T *)p
+       p

A function in atl1e_main.c was passed a const pointer
when it actually modified elements of the structure.

Change the argument to a non-const pointer.

A function in stmmac needed a __force to avoid a sparse
warning.  Added it.

      net: remove netdev_alloc_page and use __GFP_COLD · 1f2149c1
      由 Eric Dumazet 提交于 
      Given we dont use anymore the struct net_device *dev argument, and this
interface brings litle benefit, remove netdev_{alloc|free}_page(), to
debloat include/linux/skbuff.h a bit.

(Some drivers used a mix of these interfaces and alloc_pages())

When allocating a page given to device for DMA transfer (device to
memory), it makes sense to use a cold one (__GFP_COLD)

      Add appropriate <linux/prefetch.h> include for prefetch users · 70c71606
      由 Paul Gortmaker 提交于 
      After discovering that wide use of prefetch on modern CPUs
could be a net loss instead of a win, net drivers which were
relying on the implicit inclusion of prefetch.h via the list

them an explicit include via the following $0.02 script.
