Subject: xen/tmem: Use xen_page_to_gfn rather than pfn_to_gfn
X-Git-Tag: omap-for-v4.3/fixes-rc1~39^2~4

xen/tmem: Use xen_page_to_gfn rather than pfn_to_gfn

All the caller of xen_tmem_{get,put}_page have a struct page * in hand
and call pfn_to_gfn for the only benefits of these 2 functions.

Rather than passing the pfn in parameter, pass directly the page and use
directly xen_page_to_gfn.
