Add try_to_unuse_page_entry() which can be used to unuse page entries.
This needs try_to_unuse_anon() which is also added, similar to
try_to_unmap_anon().

Allow mtd block drivers to customise their ioctl functions. Also
allow the drivers to obtain the gendisk struct since ioctl
functions can need this.
This also moves the mtd ioctl functions from locked to unlocked.
As far as I can see, nothing in the mtd code has locking problems.

Knowing that the data in a given block is now unused is a useful
feature that some block drivers can take advantage of, especially

Hm, I got recently hands on a hardware where 2.6.21-rc1 based
kernels from Fedora rawhide simply do not boot as there is no
way to get to disks. I would not mind some change in behavior
although so far I can boot at least some earlier kernels.
