validate_addr() function checks whether the address returned by mmap() lies in the low or high VA space, according to whether a high addr hint was passed or not. The fix commit mentioned below changed the code in such a way that this function will always return failure when passed high_addr == 1; addr will be >= HIGH_ADDR_MARK always, we will fall down to "if (addr < HIGH_ADDR_MARK)" and return failure. Fix this.

This looks good to me. Feel free to add Reviewed-by: Donet Tom <donet...@linux.ibm.com>
