for builds on systems requiring aligned memory access. Please see
|
|
http://lists.acpica.org/pipermail/devel/2010-July/000159.html. Resolves
|
|
BZ#865013 and BZ#856856.

|
|
|
Add more platforms to the list of the ones requiring aligned memory access.
|
|
Also fix callsites where wrong assumptions where made in terms of aligment.
