Subject: x86/mm: Initialize pmd_idx in page_table_range_init_count()
From: Minfei Huang <mnfhuang@gmail.com>
commit 9962eea9e55f797f05f20ba6448929cab2a9f018 upstream.
The variable pmd_idx is not initialized for the first iteration of the
for loop.
Assign the proper value which indexes the start address.
