This patch make it possible to charge or uncharge a set of continuous
swap entries in the swap cgroup.  The number of swap entries is
specified via an added parameter.

This will be used for the THP (Transparent Huge Page) swap support.
Where a swap cluster backing a THP may be allocated and freed as a
whole.  So a set of continuous swap entries (512 on x86_64) backing one

Please use HPAGE_SIZE / PAGE_SIZE instead of hard coded number like 512.

Sure.  Will change it.

Best Regards,
Huang, Ying
