    xen/arm: Add 0x prefix when printing memory size in construct_domU
    
    Printing memory size in hex without 0x prefix can be misleading, so
    add it. Also, take the opportunity to adhere to 80 chars line length
    limit by moving the printk arguments to the next line.

    xen/arm: linker: The identitymap check should cover the whole .text.header
    
    At the moment, we are only checking that only some part of .text.header
    is part of the identity mapping. However, this doesn't take into account
    the literal pool which will be located at the end of the section.
    
    While we could try to avoid using a literal pool, in the near future we
    will also want to use an identity mapping for switch_ttbr().
    
    Not everything in .text.header requires to be part of the identity
    mapping. But it is below a page size (i.e. 4KB) so take a shortcut and
    check that .text.header is smaller than a page size.
    
    With that _end_boot can be removed as it is now unused. Take the
    opportunity to avoid assuming that a page size is always 4KB in the
    error message and comment.

    xen/arm: linker: Indent correctly _stext
    
    _stext is indented by one space more compare to the lines. This doesn't
    seem warrant, so delete the extra space.

    x86/vmx: Support for CPUs without model-specific LBR
    
    Ice Lake (server at least) has both architectural LBR and model-specific 
LBR.
    Sapphire Rapids does not have model-specific LBR at all.  I.e. On SPR and
    later, model_specific_lbr will always be NULL, so we must make changes to
    avoid reliably hitting the domain_crash().
    
    The Arch LBR spec states that CPUs without model-specific LBR implement
    MSR_DBG_CTL.LBR by discarding writes and always returning 0.
    
    Do this for any CPU for which we lack model-specific LBR information.
    
    Adjust the now-stale comment, now that the Arch LBR spec has created a way 
to
    signal "no model specific LBR" to guests.

    x86/vmx: Calculate model-specific LBRs once at start of day
    
    There is no point repeating this calculation at runtime, especially as it is
    in the fallback path of the WRSMR/RDMSR handlers.
    
    Move the infrastructure higher in vmx.c to avoid forward declarations,
    renaming last_branch_msr_get() to get_model_specific_lbr() to highlight that
    these are model-specific only.
    
    No practical change.

    xen/version: Drop compat/kernel.c
    
    kernel.c is mostly in an #ifndef COMPAT guard, because compat/kernel.c
    re-includes kernel.c to recompile xen_version() in a compat form.
    
    However, the xen_version hypercall is almost guest-ABI-agnostic; only
    XENVER_platform_parameters has a compat split.  Handle this locally, and do
    away with the re-include entirely.  Also drop the CHECK_TYPE()'s between 
types
    that are simply char-arrays in their native and compat form.
    
    In particular, this removed the final instances of obfuscation via the DO()
    macro.
    
    No functional change.  Also saves 2k of of .text in the x86 build.

    public/version: Change xen_feature_info to have a fixed size
    
    This is technically an ABI change, but Xen doesn't operate in any 
environment
    where "unsigned int" is different to uint32_t, so switch to the explicit 
form.
    This avoids the need to derive (identical) compat logic for handling the
    subop.
