This patch corrects minor spelling mistake and adjusts comment style, such as capitalizing the first letter for consistency. In addition, "error: failed to find available memory address for mapping\n" message replaces a not-quite-suitable one:"error: mmap doesn't like you\n".

No functional changes are introduced
