ubi,ubifs: sync with linux v4.2
sync with linux v4.2
commit 64291f7db5bd8150a74ad2036f1037e6a0428df2
Author: Linus Torvalds <torvalds@linux-foundation.org>
Date: Sun Aug 30 11:34:09 2015 -0700
Linux 4.2
This update is needed, as it turned out, that fastmap
was in experimental/broken state in kernel v3.15, which
was the last base for U-Boot.
