[PATCH] Fix compile for CONFIG_SYSVIPC=n or CONFIG_SYSCTL=n

[Stephen Rothwell <sfr@canb.auug.org.au>]

[-- Attachment #1: Type: text/plain, Size: 2268 bytes --]

The compat syscalls are added to sys_ni.c since they are not defined
if the above CONFIG options are off. Also, nfs would not build with
CONFIG_SYSCTL off.

Noticed by Arthur Othieno.

Linus, can we have this applied for 2.6.16.  It presumably affects sparc64
(at least for CONFIG_SYSVIPC) as well as powerpc.  The NFS fix would
affect all architectures, I think?

This has been compile tested with the CONFIG options on and off for powerpc.
