PTHREAD_STACK_MIN is not defined

[Uma Sankar]

Hi I am trying to compile ltp/testcases/kernel/sched/cfs-scheduler/
hackbench.c file and I am getting error like "error: 'PAGE_SIZE'
undeclared (first use in this function)
"
It seems macro for PTHREAD_STACK_MIN is defined as PAGE_SIZE but its
not able to find the declaration for PAGE_SIZE macro.

Any help in this regard is appreciable and find the error function and
include files below.
Thanks
