Commit Comment: block: ioctl: fix information leak to userland
Structure hd_geometry is copied to userland with 4 padding bytes
between cylinders and start fields uninitialized on 64-bit platforms.
It leads to leaking of contents of kernel stack memory.

(2.6 commit: a014741c0adfb8fb79952939ca087cf03d272bb9)
[WT: different fix from 2.6 because we could not centralize the ioctl, so
all affected drivers had to be fixed ]
