Subject: [Qemu-devel] [PATCH 1/1] apic_common: improve readability of apic_reset_common
Date: Tue, 7 Apr 2015 16:53:52 +0300 [thread overview]
Message-ID: <1428414832-3104-1-git-send-email-den@openvz.org> (raw)
Replace call of cpu_is_bsp(s->cpu) which really returns
!!(s->apicbase & MSR_IA32_APICBASE_BSP)
with directly collected value. Due to this the tracepoint
trace_cpu_get_apic_base((uint64_t)s->apicbase);
will not be hit anymore in apic_reset_common.
