_could_ then at a later "fix" these drivers which are using
vm_insert_range_buggy() to behave according to the normal vm_pgoff
offsetting simply by removing the _buggy suffix on the function
name and if that causes regressions, it gives us an easy way to revert.

ug in [7/9], where user passed length is not

it will end up overrun page array which could lead to a potential bug.
This is fixed as part of these conversion.

those error check we might end up overrun the page
array.
In rockchip/rockchip_drm_gem.c, added error check which was removed in
v1, as without this it might overrun page array. Adjusted page_count
parameter before passing it to vm_insert_range().
