[ Upstream commit 0bd81274e3f1195ee7c820ef02d62f31077c42c3 ]
The name of the local variable holding the "form2" property address conflicts with the numa_distance_table global.
This patch does 's/numa_dist_table/form2_distances/g' over the function, which also renames numa_dist_table_length to form2_distances_length.
