[PATCH] madvise() does not always return -EBADF on non-file mapped area
The madvise() system call returns -EBADF for areas which does not map to files, only for *behaviour* request MADV_WILLNEED. According to man pages, madvise returns : EBADF - the map exists, but the area maps something that isn't a file. Fixes bug 2995.
