[Xen-devel] [PATCH v4 24/39] arm/p2m: Make p2m_put_l3_page ready for altp2m

[Sergej Proskurin <proskurin@xxxxxxxxxxxxx>]

This commit extends the prototype of the function "p2m_put_l3_page" by
an additional function parameter of type "struct p2m_domain*". This is
needed as a future commit will extend the function "p2m_put_l3_page" so
that we can call "put_page" only if the p2m being modified is the
hostp2m.
