    x86: fix get_cpu_info() when built with clang

    Clang understands the GCCism in use here, but still complains that sp is
    unintialised.  In such cases, resort to the older version of this code, 
which
    directly reads %rsp into the temporary variable.

    Note that we still keep the GCCism in the default case, as it causes GCC to
    create rather better assembly.

    x86: improve annotation of autogen_entrypoints[]

    Clang complains that the __used attribute is not applicable to an extern.  
In
    this case, the only relevent attribute is that the data is constant.

    x86: fix section type mismatch in mm.c

    Clang doesn't like mixing const and non-const data in the same section.  
Move
    zero_page into .bss.page_aligned.const and wildcard .bss.page_aligned when
    linking.

    remove or annotate possibly-unused functions

    Clang notices more unused functions than GCC.

     * sh_next_page() is only used at GUEST_PAGING_LEVELS=2, so remove it from 
the
       other guest level translation units
     * rcu_batch_after() is completely unused.
     * Various of the COMPAT() generated functions are used only for their
       BUILD_BUG_ON() properties.  Annotate them all as __maybe_used.

    xen/lib.h: fix ASSERT() to build with clang

    Clang warns about a semicolon immediately following an if() clause as a
    possible mistake, and recommends putting the semicolon on a new line if it 
was
    intentional.  A newline is not an option here, so use a set of empty braces
    instead.

    hvmloader: fix scratch_alloc to avoid overlaps

    scratch_alloc() set scratch_start to the last byte of the current
    allocation.  The value of scratch_start is then reused as is (if it is
    already aligned) in the next allocation.  This result in a potential reuse
    of the last byte of the previous allocation.

    x86/altp2m: merge p2m_set_altp2m_mem_access and p2m_set_mem_access

    The altp2m subsystem in its current form duplicates much of the existing
    code present in p2m for setting mem_access permissions. In this patch we
    consolidate the two versions but keep the separate MEMOP and HVMOP 
interfaces.

    x86/mm: drop guest_{map,get_eff}_l1e() hooks

    Disallow the unmaintained and presumed broken translated-but-not-
    external paging mode combination, allowing the respective paging hooks
    to go away (which eliminates one pair of NULL callbacks in HAP mode).
    As a result of them no longer being generic paging operations, make the
    inline functions private to mm.c, dropping their struct vcpu parameters
    where suitable.

    The enforcement of the proper mode combination gets now done in
    paging_enable(), requiring shadow_domctl() to no longer call
    shadow_enable() directly.

    Also as a result support for XEN_DOMCTL_SHADOW_OP_ENABLE_TRANSLATE gets
    removed too.

    x86/nHVM: avoid NULL deref during INVLPG intercept handling

    When intercepting (or emulating) L1 guest INVLPG, the nested P2M
    pointer may be (is?) NULL, and hence there's no point in calling
    p2m_flush(). In fact doing so would cause a dereference of that NULL
    pointer at least in the ASSERT() right at the beginning of the
    function.

    While so far nothing supports hap_invlpg() being reachable from the
    INVLPG intercept paths (only INVLPG insn emulation would lead there),
    and hence the code in question (added by dd6de3ab99 ["Implement
    Nested-on-Nested"]) appears to be dead, this seems to be the change
    which can be agreed on as an immediate fix. Ideally, however, the
    problematic code would go away altogether. See thread at
    lists.xenproject.org/archives/html/xen-devel/2016-01/msg03762.html.

    x86/hvm: simplify emulation triggered by vm_event response

    Currently, after receiving a vm_event reply requesting emulation,
    the actual emulation is triggered in p2m_mem_access_check(),
    which means that we're waiting for the page fault to occur again
    before emulating. Aside from the performance impact, this
    complicates the code since between hvm_do_resume() and the second
    page fault it is possible that the latter becomes a completely
    new page fault - hence checking that EIP and the GPA match with
    the ones in the original page fault. If they don't, duplicate
    EPT fault vm_events will occur, of which a monitoring application
    needs to be aware.
    This patch makes struct arch_vm_event smaller (since we no longer
    need to track eip and gpa), removes the checking code from
    p2m_mem_access_check(), and moves the emulation in hvm_do_resume().
