According to folks on libc-alpha any program that accesses kernel headers
(asm)
in userland are broken and should be fixed. Our maintainer for Linux 2.4 
(Paul Mackerras <paulus>) has wrapped all of our asm-ppc
kernel headers in #ifdef __KERNEL__/#endif wrappers to prevent userland
programs from accessing their contents. This has revealed that procps is
broken
in that it repeatedly access PAGE_SIZE and PAGE_SHIFT from asm/page.h.
On linuxppc, we believe the following test program demonstrates that these
values can be obtained for procps without resorting to the current broken
behavior 
of accessing kernel headers...

----------------------------------------------------------
#include <stdio.h>
#include <sys/shm.h>

#define PAGE_SHIFT	12
#define PAGE_SIZE	(1UL << PAGE_SHIFT)

int i,pagesize,pageshift;

main()
{
pagesize=__getpagesize();

for(i=1; i <= 8*sizeof(int); i++) {
  if( pagesize & (1UL << i)) {
    pageshift += i;
  }
}

printf("pagesize is %d\n",pagesize);
printf("pagesize is %d\n",PAGE_SIZE);
printf("pageshift is %d\n",pageshift);
printf("pageshift is %d\n",PAGE_SHIFT);

---------------------------------------------
This code works fine on Linuxppc running glibc 2.1.95/Linux 2.4-testpre3
/gcc 2.95.3. Below is the output I get from it here...

pagesize is 4096
pagesize is 4096
pageshift is 12
pageshift is 12

Please fix procps in rawhide so we can test the fixed version before Linux
2.4
is released.
