    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

    x86/EFI: further correct FPU state handling around runtime calls
    
    We must not leave a vCPU with CR0.TS clear when it is not in fully eager
    mode and has not touched non-lazy state. Instead of adding a 3rd
    invocation of stts() to vcpu_restore_fpu_eager(), consolidate all of
    them into a single one done at the end of the function.
    
    Rename the function at the same time to better reflect its purpose, as
    the patches touches all of its occurences anyway.
    
    The new function parameter is not really well named, but
    "need_stts_if_not_fully_eager" seemed excessive to me.

    x86/EFI: fix FPU state handling around runtime calls
    
    There are two issues.  First, the nonlazy xstates were never restored
    after returning from the runtime call.
    
    Secondly, with the fully_eager_fpu mitigation for XSA-267 / LazyFPU, the
    unilateral stts() is no longer correct, and hits an assertion later when
    a lazy state restore tries to occur for a fully eager vcpu.
    
    Fix both of these issues by calling vcpu_restore_fpu_eager().  As EFI
    runtime services can be used in the idle context, the idle assertion
    needs to move until after the fully_eager_fpu check.
    
    Introduce a "curr" local variable and replace other uses of "current"
    at the same time.

    x86: correct default_xen_spec_ctrl calculation
    
    Even with opt_msr_sc_{pv,hvm} both false we should set up the variable
    as usual, to ensure proper one-time setup during boot and CPU bringup.
    This then also brings the code in line with the comment immediately
    ahead of the printk() being modified saying "irrespective of guests".

    libxc/x86/PV: don't hand through CPUID leaf 0x80000008 as is
    
    Just like for HVM the feature set should be used for EBX output, while
    EAX should be restricted to the low 16 bits and ECX/EDX should be zero.
