    gnttab: fix GNTTABOP_copy continuation handling
    
    The XSA-226 fix was flawed - the backwards transformation on rc was done
    too early, causing a continuation to not get invoked when the need for
    preemption was determined at the very first iteration of the request.
    This in particular means that all of the status fields of the individual
    operations would be left untouched, i.e. set to whatever the caller may
    or may not have initialized them to.
    
    This is part of XSA-318.

    xen/gnttab: Fix error path in map_grant_ref()
    
    Part of XSA-295 (c/s 863e74eb2cffb) inadvertently re-positioned the 
brackets,
    changing the logic.  If the _set_status() call fails, the grant_map 
hypercall
    would fail with a status of 1 (rc != GNTST_okay) instead of the expected
    negative GNTST_* error.
    
    This error path can be taken due to bad guest state, and causes net/blk-back
    in Linux to crash.
    
    This is XSA-316.

    xen/rwlock: Add missing memory barrier in the unlock path of rwlock
    
    The rwlock unlock paths are using atomic_sub() to release the lock.
    However the implementation of atomic_sub() rightfully doesn't contain a
    memory barrier. On Arm, this means a processor is allowed to re-order
    the memory access with the preceeding access.
    
    In other words, the unlock may be seen by another processor before all
    the memory accesses within the "critical" section.
    
    The rwlock paths already contains barrier indirectly, but they are not
    very useful without the counterpart in the unlock paths.
    
    The memory barriers are not necessary on x86 because loads/stores are
    not re-ordered with lock instructions.
    
    So add arch_lock_release_barrier() in the unlock paths that will only
    add memory barrier on Arm.
    
    Take the opportunity to document each lock paths explaining why a
    barrier is not necessary.
    
    This is XSA-314.

    xenoprof: limit consumption of shared buffer data
    
    Since a shared buffer can be written to by the guest, we may only read
    the head and tail pointers from there (all other fields should only ever
    be written to). Furthermore, for any particular operation the two values
    must be read exactly once, with both checks and consumption happening
    with the thus read values. (The backtrace related xenoprof_buf_space()
    use in xenoprof_log_event() is an exception: The values used there get
    re-checked by every subsequent xenoprof_add_sample().)
    
    Since that code needed touching, also fix the double increment of the
    lost samples count in case the backtrace related xenoprof_add_sample()
    invocation in xenoprof_log_event() fails.
    
    Where code is being touched anyway, add const as appropriate, but take
    the opportunity to entirely drop the now unused domain parameter of
    xenoprof_buf_space().
    
    This is part of XSA-313.

    xenoprof: clear buffer intended to be shared with guests
    
    alloc_xenheap_pages() making use of MEMF_no_scrub is fine for Xen
    internally used allocations, but buffers allocated to be shared with
    (unpriviliged) guests need to be zapped of their prior content.
