[PATCH 0/4] apply page shift to PFN instead of VA in pfn_to_virt

From: Yan Zhao

This is a tiny fix to pfn_to_virt() for some platforms.

The original implementaion of pfn_to_virt() takes PFN instead of PA as the
input to macro __va, with PAGE_SHIFT applying to the converted VA, which
is not right under most conditions, especially when there's an offset in
__va.
