    x86: assorted array_index_nospec() insertions
    
    Don't chance having Spectre v1 (including BCBS) gadgets. In some of the
    cases the insertions are more of precautionary nature rather than there
    provably being a gadget, but I think we should err on the safe (secure)
    side here.

    rangeset: make inquiry functions tolerate NULL inputs
    
    Rather than special casing the ->iomem_caps check in x86's
    get_page_from_l1e() for the dom_xen case, let's be more tolerant in
    general, along the lines of rangeset_is_empty(): A never allocated
    rangeset can't possibly contain or overlap any range.

    x86/setup: Avoid OoB E820 lookup when calculating the L1TF safe address
    
    A number of corner cases (most obviously, no-real-mode and no Multiboot

    map) can end up with e820_raw.nr_map being 0, at which point the L1TF
    calculation will underflow.

    x86/hvm/ioreq: MMIO range checking completely ignores direction flag
    
    hvm_select_ioreq_server() is used to route an ioreq to the appropriate
    ioreq server. For MMIO this is done by comparing the range of the ioreq
    to the ranges registered by the device models of each ioreq server.
    Unfortunately the calculation of the range if the ioreq completely ignores
    the direction flag and thus may calculate the wrong range for comparison.
    Thus the ioreq may either be routed to the wrong server or erroneously
    terminated by null_ops.
    
    NOTE: The patch also fixes whitespace in the switch statement to make it
          style compliant.

    x86/vlapic: Bugfixes and improvements to vlapic_{read,write}()
    
    Firstly, there is no 'offset' boundary check on the non-32-bit write path
    before the call to vlapic_read_aligned(), which allows an attacker to read
    beyond the end of vlapic->regs->data[], which is only 1024 bytes long.
    
    However, as the backing memory is a domheap page, and misaligned accesses 
get
    chunked down to single bytes across page boundaries, I can't spot any
    XSA-worthy problems which occur from the overrun.
    
    On real hardware, bad accesses don't instantly crash the machine.  Their
    behaviour is undefined, but the domain_crash() prohibits sensible testing.
    Behave more like other x86 MMIO and terminate bad accesses with appropriate
    defaults.
    
    While making these changes, clean up and simplify the the smaller-access
    handling.  In particular, avoid pointer based mechansims for 1/2-byte reads 
so
    as to avoid forcing the value to be spilled to the stack.
    
      add/remove: 0/0 grow/shrink: 0/2 up/down: 0/-175 (-175)
      function                                     old     new   delta
      vlapic_read                                  211     142     -69
      vlapic_write                                 304     198    -106
    
    Finally, there are a plethora of read/write functions in the vlapic 
namespace,
    so rename these to vlapic_mmio_{read,write}() to make their purpose more
    clear.

    x86/vmx: Avoid hitting BUG_ON() after EPTP-related domain_crash()
    
    If the EPTP pointer can't be located in the altp2m list, the domain
    is (legitimately) crashed.
    
    Under those circumstances, execution will continue and guarentee to hit the
    BUG_ON(idx >= MAX_ALTP2M) (unfortunately, just out of context).
    
    Return from vmx_vmexit_handler() after the domain_crash(), which also has 
the
    side effect of reentering the scheduler more promptly.
