conf: Introduce 'alignsize' element into xml for NVDIMM memory NVDIMM emulation will mmap the backend file, it uses host pagesize as the alignment of mapping address before, but some backends may require alignments different from the pagesize. So the 'alignsize' option is introduced to allow specification of the proper alignment: <devices> ... <memory model='nvdimm' access='shared'> <source> <path>/dev/dax0.0</path> <alignsize unit='MiB'>2</alignsize> </source> <target> <size unit='MiB'>4094</size> <node>0</node> <label> <size unit='MiB'>2</size> </label> </target> </memory> ... </devices> Signed-off-by: Luyao Zhong <luyao.zhong@intel.com> Reviewed-by: John Ferlan <jferlan@redhat.com>
