commit c26b88bf644011396b4e4f6f15901a66b87d8c19
Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx>
Date:   Wed Feb 10 14:51:25 2016 +0100

    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.

    x86: remove %z modifier from inline assembly
    
    Clang doesn't support the %z modifier.  Replace both uses with an explicit l
    suffix, and cover the changes with BUILD_BUG_ON()s

    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.
