modular nfsd requires kernel changes on sh, sparc64, x86_64

[Adrian Bunk]

Compiling and inserting a module into the currently running kernel 
should work without needing a reboot.

For nfsd this seems to work everywhere except on the sh, sparc64 
and x86_64 architectures where adding the nfsd module changes 
non-modular kernel code (checked in 2.6.4-mm1):


arch/sh/kernel/entry.S:

<--  snip  -->

...
#if !defined(CONFIG_NFSD) && !defined(CONFIG_NFSD_MODULE)
#define sys_nfsservctl          sys_ni_syscall
#endif
...

<--  snip  -->


arch/x86_64/ia32/sys_ia32.c:

<--  snip  -->

...
#if defined(CONFIG_NFSD) || defined(CONFIG_NFSD_MODULE)
/* Stuff for NFS server syscalls... */
struct nfsctl_svc32 {
        u16                     svc32_port;
        s32                     svc32_nthreads;
};

struct nfsctl_client32 {
...

<--  snip  -->


arch/sparc64/kernel/sys_sparc32.c:

<--   snip  -->

...
#if defined(CONFIG_NFSD) || defined(CONFIG_NFSD_MODULE)
/* Stuff for NFS server syscalls... */
struct nfsctl_svc32 {
        u16                     svc32_port;
        s32                     svc32_nthreads;
};

struct nfsctl_client32 {
...

<--  snip  -->
