Hi everyone
     arm:

/* gap between mmap and stack */
#define MIN_GAP (128*1024*1024UL)

The min_gap is 128M,
in the mmap_base function
unsigned long gap = rlimit(RLIMIT_STACK);

     if (gap < MIN_GAP)
         gap = MIN_GAP;
     else if (gap > MAX_GAP)
         gap = MAX_GAP;

I can not use the "128-stack_size"(M)

can i modify it to 64M?


Thanks,
jie chen
