Hi all,

After merging the net-next tree, today's linux-next build (sparc64
defconfig) failed like this:

net/core/sock.c: In function 'sock_setsockopt':
net/core/sock.c:1417:7: error: 'SO_RESERVE_MEM' undeclared (first use in this function); did you mean 'IORESOURCE_MEM'?
  case SO_RESERVE_MEM:
       ^~~~~~~~~~~~~~
       IORESOURCE_MEM
net/core/sock.c:1417:7: note: each undeclared identifier is reported only once for each function it appears in
net/core/sock.c: In function 'sock_getsockopt':
net/core/sock.c:1817:7: error: 'SO_RESERVE_MEM' undeclared (first use in this function); did you mean 'IORESOURCE_MEM'?
  case SO_RESERVE_MEM:
       ^~~~~~~~~~~~~~
       IORESOURCE_MEM

Caused by commit

  2bb2f5fb21b0 ("net: add new socket option SO_RESERVE_MEM")

arch/sparc/include/uapi/socket.h does not include uapi/asm/socket.h and
some other architectures do not as well.

I have added the following patch for today (I searched for SO_BUF_LOCK
and, of these architectures, I have only compile tested sparc64 and
sparc):

I committed the sparc part into net-next today, thanks.
