    x86/hvm: Fix altp2m_vcpu_enable_notify error handling
    
    The altp2m_vcpu_enable_notify subop handler might skip calling
    rcu_unlock_domain() after rcu_lock_current_domain().  Albeit since both
    rcu functions are no-ops when run on the current domain, this doesn't
    really have repercussions.
    
    The second change is adding a missing break that would have potentially
    enabled #VE for the current domain even if it had intended to enable it
    for another one (not a supported functionality).

    x86/shadow: correct SH_LINEAR mapping detection in sh_guess_wrmap()
    
    The fix for XSA-243 / CVE-2017-15592 (c/s bf2b4eadcf379) introduced a change
    in behaviour for sh_guest_wrmap(), where it had to cope with no shadow 
linear
    mapping being present.
    
    As the name suggests, guest_vtable is a mapping of the guests pagetable, not
    Xen's pagetable, meaning that it isn't the pagetable we need to check for 
the
    shadow linear slot in.
    
    The practical upshot is that a shadow HVM vcpu which switches into 4-level
    paging mode, with an L4 pagetable that contains a mapping which aliases 
Xen's
    SH_LINEAR_PT_VIRT_START will fool the safety check for whether a 
SHADOW_LINEAR
    mapping is present.  As the check passes (when it should have failed), Xen
    subsequently falls over the missing mapping with a pagefault such as:
    
        (XEN) Pagetable walk from ffff8140a0503880:
        (XEN)  L4[0x102] = 000000046c218063 ffffffffffffffff
        (XEN)  L3[0x102] = 000000046c218063 ffffffffffffffff
        (XEN)  L2[0x102] = 000000046c218063 ffffffffffffffff
        (XEN)  L1[0x103] = 0000000000000000 ffffffffffffffff
    
    This is part of XSA-243.

    x86: don't wrongly trigger linear page table assertion
    
    _put_page_type() may do multiple iterations until its cmpxchg()
    succeeds. It invokes set_tlbflush_timestamp() on the first
    iteration, however. Code inside the function takes care of this, but
    - the assertion in _put_final_page_type() would trigger on the second
      iteration if time stamps in a debug build are permitted to be
      sufficiently much wider than the default 6 bits (see WRAP_MASK in
      flushtlb.c),
    - it returning -EINTR (for a continuation to be scheduled) would leave
      the page inconsistent state (until the re-invocation completes).
    Make the set_tlbflush_timestamp() invocation conditional, bypassing it
    (for now) only in the case we really can't tolerate the stamp to be
    stored.
    
    This is part of XSA-240.

    xen/arm: p2m: Add more debug in get_page_from_gva
    
    The function get_page_from_gva is used by copy_*_guest helpers to
    translate a guest virtual address to a machine physical address and take
    reference on the page.
    
    There are a couple of errors paths that will return the same value making
    it difficult to know the exact error. Add more debug in each error patch
    only for debug-build.
    
    This should help narrowing down the intermittent failure with the
    hypercall GNTTABOP_copy (see [1]).

    xen/arm: mm: Change the return value of gvirt_to_maddr
    
    Currently, gvirt_to_maddr return -EFAULT when the translation failed.
    It might be useful to return the PAR_EL1 (Physical Address Register)
    in such a case to get a better idea of the reason.
    
    So modify the return value to use 0 on success or return the PAR on
    failure.
    
    The callers are modified to reflect the change of the return value.
    
    Note that with the change in gvirt_to_maddr, ma needs to be initialized
    to avoid GCC been confused (i.e value may be uninitialized) with the new
    construction.
