[PATCH v3 1/8] arch: Use asm-generic/socket.h when possible

From: Deepa Dinamani
Date: Mon Jan 07 2019 - 22:27:37 EST

Many architectures maintain an arch specific copy of the
file even though there are no differences with the asm-generic
one. Allow these architectures to use the generic one instead.
