MFC r269487 (by issyl0):
  Add generic list, status, load and unload docs to gpart(8)

  - In the style of gmirror(8).
  PR:		docs/191534

MFC r269852:
  Add sysctl and loader tunable kern.geom.part.mbr.enforce_chs that is set
  by default. It can be used to disable automatic alignment to CHS geometry,
  that GEOM_PART_MBR does.
