I've got an oops...
this is my dev-kernel in 3.5-rc5 + some work to be able to boot on my board
NB: If I use ubi_format it's ok.
the mtd1 device has 1984 PEB
the 4 last are UBI reserved + BBT
I didn't test without your patch, but anyway something is wrong there.

Provide count_leading/trailing_zeros() macros based on extant arch bit scanning
functions rather than reimplementing from scratch in MPILIB.
Whilst we're at it, turn count_foo_zeros(n, x) into n = count_foo_zeros(x).
Also move the definition to asm-generic as other people may be interested in
