Title:
  Fix handling of multipathed disks with 4k-sectors

Status in multipath-tools package in Ubuntu:
  New

Bug description:
  The packages for libparted and kpartx don't have the patches for using
  device-mapper (multipath/LVM) on 4k-sector disks (generally: 'non
  512-byte sector disks')

  This causes the number of sectors of each device-mapper partition to be 1/8th (512/4096) of that expected.
  These 3 errors were identified:
  1) Partition sizes on multipath/LVM are 1/8th of the intended size 
  2) The filesystem on the underlying device is not-accessible (only in the dm mapped device)
  3) grub-install fails w/ 'Unknown filesystem'

  The 2 patches attached contains upstream patches from parted and
  multipath-tools, and fix the issues (the installation finishes without
  errors and the system boots).
