fs/proc/kcore.c: don't add modules range to kcore if it's equal to vm…
…core range On some ARCHs modules range is eauql to vmalloc range. E.g on i686 "#define MODULES_VADDR VMALLOC_START" "#define MODULES_END VMALLOC_END" This will cause 2 duplicate program segments in /proc/kcore, and no flag to indicate they are different. This is confusing. And usually people who need check the elf header or read the content of kcore will check memory ranges. Two program segments which are the same are unnecessary. So check if the modules range is equal to vmalloc range. If so, just skip adding the modules range.
