[PATCH] do_mounts.c - compiler warning, comments, cramfs

[kuebelr]

This patch tweaks a few things in do_mounts.c:

-change_floppy() is defined but not used if neither CONFIG_BLK_DEV_RAM
	or CONFIG_BLK_DEV_FD are defined
-since the gzip code is already in the kernel, why not do away w/ the
	BUILD_CRAMDISK stuff and always support compressed images
-one incorrect comment changed
-one repeated NOTE removed

If no one yells at me for this, I will submit it to the patch monkey.

Rob.
