[PATCH v2 0/2] xen/list: some fixes in list.h

[Juergen Gross <jgross@xxxxxxxx>]

Patch 1 is a fix for an undefined behavior reported by Andrew. I think
this patch should be considered for 4.20.

Patch 2 is fixing wrong comments in list.h I stumbled over when doing
patch 1. As it is absolutely no risk involved with this patch, I think
it should be 4.20 material, too.

Changes in V2:
- comments addressed

Juergen Gross (2):
  xen/list: avoid UB in list iterators
  xen/list: fix comments in include/xen/list.h
