PATCH 1/1 tmpfs fixes against 2.4.6-pre

Hi Linus,

the appended patch fixes several tmpfs problems:

1) writing out of a mapping of a tmpfs file into the same file can deadlock
2) shmem_remount_fs garbles parameters which are not supplied
3) shmem_file_setup should check the maximum size

Please apply
Christoph
