    xen: remove empty softirq_init()
    
    softirq_init() is empty since Xen 4.1. Remove it together with its call
    sites.

    AMD/IOMMU: drop redundant code
    
    The level 1 special exit path is unnecessary in iommu_pde_from_dfn() -
    the subsequent code takes care of this case quite fine.

    dom0-build: fix build with clang5
    
    With non-empty CONFIG_DOM0_MEM clang5 produces
    
    dom0_build.c:344:24: error: use of logical '&&' with constant operand 
[-Werror,-Wconstant-logical-operand]

    1 error generated.
    
    Obviously neither of the two suggestions are an option here. Oddly
    enough swapping the operands of the && helps, while e.g. casting or
    parenthesizing doesn't. Another workable variant looks to be the use of
    !! on the constant.

    tools/libxl: Combine legacy CPUID handling logic
    
    While we are in the process of overhauling boot time CPUID/MSR handling, the
    existing logic is going to have to remain in roughly this form for backwards
    compatibility.
    
    Fold libxl__cpuid_apply_policy() and libxl__cpuid_set() together into a 
single
    libxl__cpuid_legacy() to reduce the complexity for callers.
    
    No functional change.

commit dacb80f9757c011161cec6609f39837c9ea8caa8

    tools/libxl: Remove libxl_cpuid_{set,apply_policy}() from the API
    
    These functions should never have been exposed.  They don't have external
    users, and can't usefully be used for several reasons.
    
    Move libxl_cpuid_{set,apply_policy}() to being internal functions, and leave
    an equivalent of the nop stubs in the API for caller compatibility.
