David Chinner ee1c090825 [XFS] Fix superblock features2 field alignment problem 
Due to the xfs_dsb_t structure not being 64 bit aligned, the last field of
the on-disk superblock can vary in location This causes problems when the
filesystem gets moved to a different platform, or there is a 32 bit
userspace and 64 bit kernel.

This patch detects the defect at mount time, logs a warning such as:

XFS: correcting sb_features alignment problem

in dmesg and corrects the problem so that everything is OK. it also
blacklists the bad field in the superblock so it does not get used for
something else later on.
