From 4c08edd305019061bf1ac95ce089497bdbb8b8ac Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Wed, 6 Nov 2013 10:00:05 -0800 Subject: [PATCH] x86, hyperv: Move a variable to avoid an unused variable warning The variable hv_lapic_frequency causes an unused variable warning if CONFIG_X86_LOCAL_APIC is disabled. Since the variable is only used inside a small if statement, move the declaration of that variable into the if statement itself. Cc: K. Y.
