[GIT PULL] cache invalidation error, unlock blocks on power up, point hack

[Jared Hulbert]

David,

Would you please pull from my git tree: /users/jehulber/mtd.git

It has three patches that have been reviewed but not applied.

(1) The cache invalidation error fix from Massimo Cirillo
(2) Unlock block on powerup on Intel NOR from Justin Treon
(3) Physical address from ->point() from Jared Hulbert

Thanks,
  Jared
