Am I missing something? Next time, please start fresh new thread instead of being a part of another discussion. At least in my Gmail thread's view, your post is placed under Himanshu's. About your question, I find that a bit strange. In what condition do you test those codes? And do you see it fail for all addresses in 0-0xc0000000 range or just few of them? And btw, we're talking about x86 32 bit, right? -- regards, Mulyadi Santosa Freelance Linux trainer blog: the-hydra.blogspot.com -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
