[PATCH] target/i386/monitor: synchronize cpu before printing lapic state


From: David Woodhouse
Subject: [PATCH] target/i386/monitor: synchronize cpu before printing lapic state
Date: Thu, 26 Oct 2023 16:39:51 +0100
User-agent: Evolution 3.44.4-0ubuntu2

From: David Woodhouse <dwmw@amazon.co.uk>

Where the local APIC is emulated by KVM, we need kvm_get_apic() to pull
the current state into userspace before it's printed. Otherwise we get
stale values.
