[Xen-devel] [PATCH 0/9] Use vm_insert_range

[Souptick Joarder <jrdr.linux@xxxxxxxxx>]

Previouly drivers have their own way of mapping range of
kernel pages/memory into user vma and this was done by
invoking vm_insert_page() within a loop.

As this pattern is common across different drivers, it can
be generalized by creating a new function and use it across
the drivers.

vm_insert_range is the new API which will be used to map a
range of kernel memory/pages to user vma.

All the applicable places are converted to use new vm_insert_range
in this patch series.
