staging: vc04_services: Convert kmap() to kmap_local_page()

Browse source

The use of kmap() is being deprecated in favor of kmap_local_page()
where it is feasible. In file interface/vchiq_arm/vchiq_arm.c,
function free_pagelist() calls kmap() / kunmap() from two places.

With kmap_local_page(), the mapping is per thread, CPU local and not
globally visible. Therefore, free_pagelist() is a function where the
use of kmap_local_page() in place of kmap() is correctly suited.

Convert to kmap_local_page() but, instead of open coding it, use the
memcpy_to_page() helper.
