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

[David Woodhouse <dwmw2@infradead.org>]

[-- Attachment #1: Type: text/plain, Size: 1058 bytes --]

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.
