[PATCH 14/48] staging: etnaviv: use vm_insert_page() rather than vm_insert_mixed()

[Lucas Stach]

From: Russell King <rmk+ker...@arm.linux.org.uk>

We're only ever going to insert using a pointer to a struct page.  Use
vm_insert_page() rather than converting back and forth between a
struct page and a PFN.
