3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Russ Anderson <[email protected]> commit 5a51467b146ab7948d2f6812892eac120a30529c upstream. uv_gpa_to_soc_phys_ram() was inadvertently ignoring the shift values. This fix takes the shift into account.
