The previous patch series had some code which was actually present in the tree
after addition of XSA-99. Please ignore the older patch series and have a look
at this patch series.

[PATCH v0 1/3] mem_access: modifications to mem_event enable API.
This patch modifies the xc_mem_event_enable API by -
 1. adding shared ring init.
 2. clearing ring page.
 3. replacing calls to deprecated API's.
 4. updating the xc_mem_event_enable API to have simmilar signature with other
    mem_event API's (This was my personal choice and is certainly debatable).

[PATCH v0 2/3] mem_event: Added new helper API to teardown mem event and unmap 
ring_page.
This patch adds a new xc_mem_event_teardown API to teardown the mem event setup
for the PAGING, ACCESS and SHARING HVM params.

[PATCH v0 3/3] xenpaging: updated code to use safer mem_event API's for setup 
and teardown.
This patch simply updates the code to use the newly created API's.
