Hi all,

On Linux-SCSI over the last few days I have been discussing a couple of
problems with the 2.6.2 megaraid driver. This patch fixes the problem
that the /proc files were being created in the wrong place, the reason
for this is that the /proc/megaraid directory was being created too
late, so it has been moved earlier in the initialisation sequence. There
has been one comment made about the #ifdef CONFIG_PROC_FS not being
needed, but if they are removed then I would also need to remove the
error when we can't create it, since it always "fails" to create a proc
entry when CONFIG_PROC_FS is not set. Please let me know if you would
like this re-submitted.

patch is attached and below.
