I have two more patches to add to the original series of 7 patches
([PATCH 0 OF 7] DM RAID updates).  These two should be added to the
end of the series.

Use 64-bit variable for 'failed_devices'.

'failed_devices' is a 64-bit field in the superblock.  The corresponding
function local variable must also be 64-bit.
