From 70907b00e6b16f7bf6407c3f58a06473209a1843 Mon Sep 17 00:00:00 2001 From: Marc Jones Date: Wed, 28 Oct 2020 17:00:31 -0600 Subject: [PATCH] soc/intel/xeon_sp: Call common soc_get_num_cpus() Use a common function to get the number of CPUs for each soc. This removes a #if for different function names in the common code.
