[I mailed to both tech-kern and port-sparc.]

 Some userland programs uses NBPG.

I found a problem in sparc/include/params.h:

 > #if   defined(SUN4M) && defined(SUN4C) && defined(SUN4)
 > #	define CPU_ISSUN4M	(cputyp == CPU_SUN4M)
 > #	define CPU_ISSUN4C	(cputyp == CPU_SUN4C)
 > #	define CPU_ISSUN4	(cputyp == CPU_SUN4)
 > #	define CPU_ISSUN4OR4C	(cputyp == CPU_SUN4 || cputyp == CPU_SUN4C)
 > #	define CPU_ISSUN4COR4M	(cputyp == CPU_SUN4C || cputyp == CPU_SUN4M)
 > #	define NBPG		nbpg
 > #	define PGOFSET		pgofset
 > #	define PGSHIFT		pgshift

"nbpg" is a global variable in kernel!

I found this problem while using shm* function because
/usr/include/sys/shm.h says:

  > #define SHMLBA	CLBYTES	/* Segment low boundry address multiple XXX */

and 

 > #define	CLBYTES		(CLSIZE*NBPG)

This is not enclosed #ifdef _KERNEL

Perhaps we should be replace by this:

#ifdef _KERNEL
#define	CLBYTES		(CLSIZE*NBPG)
#else
#define	CLBYTES		(CLSIZE * sysconf(_SC_PAGESIZE))
#endif

 Perhaps many .h file is referring NBPG directly.
