Cannot compile without sysctl (+semi-patch)

[Jan Engelhardt]

Hi,


in trying to make the smallest possible kernel for an old pc's needs (read: 
386sx) disabling sysctl support (CONFIG_SYSCTL) does not work, sys_setgroups 
and sys_setgroups16 still require it. (I get a linking error.)
It's not a blocker, but it would be nice if this got wrapped up in #ifdef or 
something :-) so that either sysctl is always on or sys_setgroups behaves a 
little different.

Preferably:
include/linux/limits.h:
#ifdef __KERNEL__
extern int ngroups_max;
# define NGROUPS_MAX ngroups_max
#else
# define NGROUPS_MAX __NGROUPS_MAX
#endif

to

#if defined(__KERNEL__) && defined(CONFIG_SYSCTL)
# define NGROUPS_MAX ngroups_max
#else
# define NGROUPS_MAX __NGROUPS_MAX
#endif
