    arm: read/write rank->vcpu atomically
    
    We don't need a lock in vgic_get_target_vcpu anymore, solving the
    following lock inversion bug: the rank lock should be taken first, then
    the vgic lock. However, gic_update_one_lr is called with the vgic lock
    held, and it calls vgic_get_target_vcpu, which tries to obtain the rank
    lock.

commit 79903e50dba9e7442c9b7ca424661bb020e9dbf2
Author: Jan Beulich <jbeulich@xxxxxxxx>

    x86emul: catch exceptions occurring in stubs
    
    Before adding more use of stubs cloned from decoded guest insns, guard
    ourselves against mistakes there: Should an exception (with the
    noteworthy exception of #PF) occur inside the stub, forward it to the
    guest.
    
    Since the exception fixup table entry can't encode the address of the
    faulting insn itself, attach it to the return address instead. This at
    once provides a convenient place to hand the exception information
    back: The return address is being overwritten by it before branching to
    the recovery code.
    
    Take the opportunity and (finally!) add symbol resolution to the
    respective log messages (the new one is intentionally not being coded
    that way, as it covers stub addresses only, which don't have symbols
    associated).
    
    Also take the opportunity and make search_one_extable() static again.

    x86/hypercall: Move hypercall continuation logic
    
    The newly-repurposed arch/x86/hypercall.c is a more appropriate place for 
the

    This is purely code motion.

    x86/hypercall: Make the HVM hcall_64bit boolean common
    
    HVM guests currently make use of arch.hvm_vcpu.hcall_64bit to track the ABI 
of
    the hypercall in use.
    
    The rest of Xen deals in terms of the comat ABI or not, so rename the 
boolean
    and make it common, guared by CONFIG_COMPAT to avoid bloat if a compat ABI 
is
    not wanted/needed.
    
    Set hcall_compat uniformly for PV guests as well as HVM guests.  This 
removes
    the remaining piece of guest-type-specific knowledge from
    hypercall_create_continuation(), allowing it to operate only in terms of the
    hypercall ABI in use.

    arm/hypercall: Use the common hcall_preempted boolean
    
    With hcall_preempted having just been made common, ARM can use use it to
    simplify its hypercall handling.
    
    This simplifies the continuation logic and removes the risk of accidentally
    skipping multiple instructions.

    x86/hypercall: Make the HVM hcall_preempted boolean common
    
    HVM guests currently make use of arch.hvm_vcpu.hcall_preempted to track
    hypercall preemption in struct vcpu.  Move this boolean to being common at 
the
    top level of struct vcpu, which will allow it to be reused elsewhere.
    
    Alter the PV preemption logic to use this boolean.  This simplifies the code
    by removing guest-type-specific knowledge, and removes the risk of 
accidently
    skipping backwards or forwards multiple times and corrupting %rip.
    
    In pv_hypercall() the old_rip bodge can be removed, and parameter clobbering
    can happen based on a more obvious condition.
