. libc: add vfs_mmap, a way for vfs to initiate mmap()s. This is a good special case to have as vfs is a slightly different client from regular user processes. It doesn't do it for itself, and has the dev & inode info already so the callback to VFS for the lookup isn't necessary. So it has different info to have to give to VM. . libc: also add minix_mmap64() that accepts a 64-bit offset, even though our off_t is still 32 bit now. . On exec() time, try to mmap() in the executable if available. (It is not yet available in this commit.) . To support mmap(), add do_vm_call that allows VM to lookup (to ino+dev), do i/o from and close FD's on behalf of other processes. Change-Id: I831551e45a6781c74313c450eb9c967a68505932
