[PATCH net-next] powerpc: use asm-generic/socket.h as much as possible

From: Stephen Rothwell <hidden>
Date: 2017-05-31 05:43:38

asm-generic/socket.h already has an exception for the differences that
powerpc needs, so just include it after defining the differences.

Build tested using powerpc allyesconfig, pseries_le_defconfig, 32 bit
and 64 bit allnoconfig and ppc44x_defconfig builds.

Dave, this is on top of the net-next tree and I am sending it to you
since it would produce a conflict if it was merged via the powerpc tree.

Did you boot it and test that userspace was happy doing sockety things?

No, sorry.

The patch was done by inspection, but it is pretty obvious ... here is
