[Xen-devel] [PATCH v5 0/4] x86/HVM: fix various aspects of APIC emulation

1: fix miscellaneous aspects of x2APIC emulation
2: fix ID handling of x2APIC emulation
3: a few type adjustments
4: don't silently accept bad vectors

Signed-off-by: Jan Beulich <jbeulich@xxxxxxxx>
v5: 1st patch extended, parts of 2nd patch moved to 3rd. See
   individual patches for specifics.
v4: 2nd patch partly re-done (see patch for details), previously
   separate 4th patch now integrated.
v3: 1st patch extended (see patch for details), new 3rd patch.
v2: Monolithic patch broken up. Generate #GP on invalid APIC base
    MSR transitions.Correct ID and LDR after domain restore (if
    necessary); as stated previously the only compatibility problem this
    creates is when migrating a VM _to_ an unfixed (i.e. old) hypervisor,
    a scenario which supposedly isn't supported.
