commit 25eb5eec796f5a965fda37c2968b3b7dd738eb72

    xen: Fix inconsistent callers of panic()
    
    Callers are inconsistent with whether they pass a newline to panic(),
    including adjacent calls in the same function using different styles.
    
    painc() not expecting a newline is inconsistent with most other printing
    functions, which is most likely why we've gained so many inconsistencies.
    
    Switch panic() to expect a newline, and update all callers which currently
    lack a newline to include one.
    
    This actually reduces the size of .rodata (0x07e3e8 down to 0x07e3a8) 
because
    a number of strings are passed to both panic() and printk().  As they
    previously differed by \n alone, they couldn't be merged.

    SVM: limit GIF=0 region
    
    Use EFLAGS.IF for most ordinary purposes; there's in particular no need
    to unduly defer NMI/#MC. Clear GIF only immediately before VMRUN itself.
    This has the additional advantage that svm_stgi_label now indeed marks
    the only place where GIF gets set.
    
    Note regarding the main STI placement: Quite counterintuitively the
    host's EFLAGS.IF continues to have a meaning while the guest runs; see
    PM Vol 2 section "Physical (INTR) Interrupt Masking in EFLAGS". Hence we
    need to set the flag for the duration of time being in guest context.
    However, SPEC_CTRL_ENTRY_FROM_HVM wants to be carried out with EFLAGS.IF
    clear.
    
    Note regarding the main STGI placement: It could be moved further up,
    but at present SPEC_CTRL_EXIT_TO_HVM is not NMI/#MC-safe.

    x86/HVM: split page straddling emulated accesses in more cases
    
    Assuming consecutive linear addresses map to all RAM or all MMIO is not
    correct. Nor is assuming that a page straddling MMIO access will access
    the same emulating component for both parts of the access. If a guest
    RAM read fails with HVMTRANS_bad_gfn_to_mfn and if the access straddles
    a page boundary, issue accesses separately for both parts.
    
    The extra call to known_gla() from hvmemul_write() is just to preserve
    original behavior; for consistency the check also gets added to
    hvmemul_rmw() (albeit I continue to be unsure whether we wouldn't better
    drop both).
    
    Note that the correctness of this depends on the MMIO caching used
    elsewhere in the emulation code.

    It can easily be expressed through hvm_copy_from_guest_linear(), and in

    x86/HVM: meet xentrace's expectations on emulation event data
    
    According to the logic in hvm_mmio_assist_process(), 64 bits of data are
    expected with 64-bit addresses, and 32 bits of data with 32-bit ones. I
    don't think this is very reasonable, but I'm also not going to touch the
    consumer side, the more that it is anyway not very helpful for the code
    here to only ever supply 32 bits of data (despite the field being 64
    bits wide, and having been even in the 32-bit days of Xen).
