From 8091c1f8ea2374695c105591179b1269fb5f2fbb Mon Sep 17 00:00:00 2001 From: Andreas Ruprecht Date: Wed, 20 Aug 2014 10:16:01 +0200 Subject: x86/apic/uv: Remove unnecessary #ifdef In the file x2apic_uv_x.c, some code is compiled conditionally depending on CONFIG_SMP. However, the file is only built, if CONFIG_X86_UV is enabled. CONFIG_X86_UV depends on CONFIG_NUMA, which itself depends on CONFIG_SMP, so the #ifdef will always evaluate to true, if the file is compiled. Thus, it is unnecessary and can be removed.

In case when thermal monitoring is handled by SMI, we get to know it via printk(). Currently it gives the message at both cases, but its okay if we get it only once and no need to get the same message at every time system resumes. So, limit showing this message only at system boot time by avoid showing at system resume and reduce abusing kernel log buffer.
