    x86/vvmx: Fix nested virt on VMCS-Shadow capable hardware
    
    c/s e9986b0dd "x86/vvmx: Simplify per-CPU memory allocations" had the wrong
    indirection on its pointer check in nvmx_cpu_up_prepare(), causing the
    VMCS-shadowing buffer never be allocated.  Fix it.
    
    This in turn results in a massive quantity of logspam, as every virtual
    vmentry/exit hits both gdprintk()s in the *_bulk() functions.
    
    Switch these to using printk_once(), but still only in debug builds.  The size
    of the buffer is chosen at compile time, so complaining about it repeatedly is
    of no benefit.
    
    Finally, drop the runtime NULL pointer checks.  It is not terribly appropriate
    to be repeatedly checking infrastructure which is set up from start-of-day,
    and in this case, actually hid the above bug.

    x86/atomic: Improvements and simplifications to assembly constraints
    
     * Constraints in the form "=r" (x) : "0" (x) can be folded to just "+r" (x)
     * Switch to using named parameters (mostly for legibility) which in
       particular helps with...
     * __xchg(), __cmpxchg() and __cmpxchg_user() modify their memory operand, so
       must list it as an output operand.  This only works because they each have
       a memory clobber to give the construct full compiler-barrier properties.
     * Every memory operand has an explicit known size.  Letting the compiler see
       the real size rather than obscuring it with __xg() allows for the removal
       of the instruction size suffixes without introducing ambiguity.
     * Drop semicolons after lock prefixes.
     * Other misc style changes.

    xen/percpu: Make DECLARE_PER_CPU() and __DEFINE_PER_CPU() common
    
    These macros are identical across the architectures, and shouldn't be separate
    from the DEFINE_PER_CPU*() infrastructure.
    
    This converts the final asm/percpu.h includes, which were all using
    DECLARE_PER_CPU(), to include xen/percpu.h instead.

    x86/xpti: Don't leak TSS-adjacent percpu data via Meltdown
    
    The XPTI work restricted the visibility of most of memory, but missed a few
    aspects when it came to the TSS.
    
    Given that the TSS is just an object in percpu data, the 4k mapping for it
    created in setup_cpu_root_pgt() maps adjacent percpu data, making it all
    leakable via Meltdown, even when XPTI is in use.
    
    Furthermore, no care is taken to check that the TSS doesn't cross a page
    boundary.  As it turns out, struct tss_struct is aligned on its size which
    does prevent it straddling a page boundary.
    
    Rework the TSS types while making this change.  Rename tss_struct to tss64, to
    mirror the existing tss32 structure we have in HVM's Tast Switch logic.  Drop
    tss64's alignment and __cacheline_filler[] field.
    
    Introduce tss_page which contains a single tss64 and keeps the rest of the
    page clear, so no adjacent data can be leaked.  Move the definition from
    setup.c to traps.c, which is a more appropriate place for it to live.

    xen/page_alloc: Keep away MFN 0 from the buddy allocator
    
    Combining of buddies happens only such that the resulting larger buddy
    is still order-aligned. To cross a zone boundary while merging, the
    implication is that both the buddy [0, 2^n-1] and the buddy
    [2^n, 2^(n+1)-1] are free.
    
    Ideally we want to fix the allocator, but for now we can just prevent
    adding the MFN 0 in the allocator to avoid merging across zone
    boundaries.
    
    On x86, the MFN 0 is already kept away from the buddy allocator. So the
    bug can only happen on Arm platform where the first memory bank is
    starting at 0.
    
    As this is a specific to the allocator, the MFN 0 is removed in the common code
    to cater all the architectures (current and future).
