    libacpi: report PCI slots as enabled only for hotpluggable devices
    
    DSDT for qemu-xen lacks _STA method of PCI slot object. If _STA method
    doesn't exist then the slot is assumed to be always present and active
    which in conjunction with _EJ0 method makes every device ejectable for
    an OS even if it's not the case.
    
    qemu-kvm is able to dynamically add _EJ0 method only to those slots
    that either have hotpluggable devices or free for PCI passthrough.
    As Xen lacks this capability we cannot use their way.
    
    qemu-xen-traditional DSDT has _STA method which only reports that
    the slot is present if there is a PCI devices hotplugged there.
    This is done through querying of its PCI hotplug controller.
    qemu-xen has similar capability that reports if device is "hotpluggable
    or absent" which we can use to achieve the same result.

    xen/sched: fix csched2_deinit_pdata()
    
    Commit 753ba43d6d16e688 ("xen/sched: fix credit2 smt idle handling")
    introduced a regression when switching cpus between cpupools.
    
    When assigning a cpu to a cpupool with credit2 being the default
    scheduler csched2_deinit_pdata() is called for the credit2 private data
    after the new scheduler's private data has been hooked to the per-cpu
    scheduler data. Unfortunately csched2_deinit_pdata() will cycle through
    all per-cpu scheduler areas it knows of for removing the cpu from the
    respective sibling masks including the area of the just moved cpu. This
    will (depending on the new scheduler) either clobber the data of the
    new scheduler or in case of sched_rt lead to a crash.
    
    Avoid that by removing the cpu from the list of active cpus in credit2
    data first.
    
    The opposite problem is occurring when removing a cpu from a cpupool:
    init_pdata() of credit2 will access the per-cpu data of the old
    scheduler.

    x86/IRQ: avoid UB (or worse) in trace_irq_mask()
    
    Dynamically allocated CPU mask objects may be smaller than cpumask_t, so
    copying has to be restricted to the actual allocation size. This is
    particulary important since the function doesn't bail early when tracing
    is not active, so even production builds would be affected by potential
    misbehavior here.
    
    Take the opportunity and also
    - use initializers instead of assignment + memset(),
    - constify the cpumask_t input pointer,
    - u32 -> uint32_t.

    x86/boot: Fix latent memory corruption with early_boot_opts_t
    
    c/s ebb26b509f "xen/x86: make VGA support selectable" added an #ifdef
    CONFIG_VIDEO into the middle the backing space for early_boot_opts_t,
    but didn't adjust the structure definition in cmdline.c
    
    This only functions correctly because the affected fields are at the end
    of the structure, and cmdline.c doesn't write to them in this case.
    
    To retain the slimming effect of compiling out CONFIG_VIDEO, adjust
    cmdline.c with enough #ifdef-ary to make C's idea of the structure match
    the declaration in asm.  This requires adding __maybe_unused annotations
    to two helper functions.

    x86/vmx: correctly gather gs_shadow value for current vCPU
    
    Currently the gs_shadow value is only cached when the vCPU is being 
scheduled
    out by Xen. Reporting this (usually) stale value through vm_event is 
incorrect,
    since it doesn't represent the actual state of the vCPU at the time the 
event
    was recorded. This prevents vm_event subscribers from correctly finding 
kernel
    structures in the guest when it is trapped while in ring3.
    
    Refresh shadow_gs value when the context being saved is for the current 
vCPU.
