    x86: guard against #NM
    
    Just in case we still don't get CR0.TS handling right, prevent a host
    crash by honoring exception fixups in do_device_not_available(). This
    would in particular cover emulator stubs raising #NM.

    x86/HVM: don't cause #NM to be raised in Xen
    
    The changes for XSA-267 did not touch management of CR0.TS for HVM
    guests. In fully eager mode this bit should never be set when
    respective vCPU-s are active, or else hvmemul_get_fpu() might leave it
    wrongly set, leading to #NM in hypervisor context.
    
    {svm,vmx}_enter() and {svm,vmx}_fpu_dirty_intercept() become unreachable
    this way. Explicit {svm,vmx}_fpu_leave() invocations need to be guarded
    now.
    
    With no CR0.TS management necessary in fully eager mode, there's also no
    need anymore to intercept #NM.

    libxl: restore passing "readonly=" to qemu for SCSI disks
    
    A read-only check was introduced for XSA-142, commit ef6cb76026 ("libxl:
    relax readonly check introduced by XSA-142 fix") added the passing of
    the extra setting, but commit dab0539568 ("Introduce COLO mode and
    refactor relevant function") dropped the passing of the setting again,
    quite likely due to improper re-basing.
    
    Restore the readonly= parameter to SCSI disks.  For IDE disks this is
    supposed to be rejected; add an assert.  And there is a bare ad-hoc
    disk drive string in libxl__build_device_model_args_new, which we also
    update.
    
    This is XSA-266.

    x86: Refine checks in #DB handler for faulting conditions
    
    One of the fix for XSA-260 (c/s 75d6828bc2 "x86/traps: Fix handling of #DB
    exceptions in hypervisor context") added some safety checks to help avoid
    livelocks of #DB faults.
    
    While a General Detect #DB exception does have fault semantics, hardware
    clears %dr7.gd on entry to the handler, meaning that it is actually safe to
    return to.  Furthermore, %dr6.gd is guest controlled and sticky (never 
cleared
    by hardware).  A malicious PV guest can therefore trigger the fatal_trap() 
and
    crash Xen.
    
    Instruction breakpoints are more tricky.  The breakpoint match bits in %dr6
    are not sticky, but the Intel manual warns that they may be set for
    non-enabled breakpoints, so add a breakpoint enabled check.
    
    Beyond that, because of the restriction on the linear addresses PV guests 
can
    set, and the fault (rather than trap) nature of instruction breakpoints
    (i.e. can't be deferred by a MovSS shadow), there should be no way to
    encounter an instruction breakpoint in Xen context.  However, for extra
    robustness, deal with this situation by clearing the breakpoint 
configuration,
    rather than crashing.
    
    This is XSA-265

    While unlikely, it is not impossible for a multi-vCPU guest to leverage
    bypasses of preemption checks to drive Xen into an unbounded loop.
