    xen/pdx: Introduce helper to convert MFN <-> PDX

    No functional change intended.
    
    While we are here, use PFN_DOWN() rather than open coding it.

    x86/mm: skip incrementing mfn if it is not a valid mfn
    
    In a follow-up patch, some callers will be switched to pass
    INVALID_MFN instead of zero for non-present mappings. So skip
    incrementing mfn if it is not a valid one.

    x86/XPTI: reduce .text.entry
    
    This exposes less code pieces and at the same time reduces the range
    covered from slightly above 3 pages to a little below 2 of them.
    
    The code being moved is unchanged, except for the removal of trailing
    blanks, insertion of blanks between operands, and a pointless q suffix
    from "retq".
    
    A few more small pieces could be moved, but it seems better to me to
    leave them where they are to not make it overly hard to follow code
    paths.

    x86: log XPTI enabled status
    
    At the same time also report the state of the two defined
    ARCH_CAPABILITIES MSR bits. To avoid further complicating the
    conditional around that printk(), drop it (it's a debug level one only
    anyway).
    
    Issue the main message without any XENLOG_*, and also drop XENLOG_INFO
    from the respective BTI message, to make sure they're visible at default
    log level also in release builds.

    This reduces code volume, and has a minor improvement on compiled size,
    probably due to the removal of several temporary variables.

    xen/public: Rename xen_domctl_createdomain.config to arch
    
    This is a tools only hypercall so fine to change.  Altering the name avoids
    having confusing code such as config->config all over the hypervisor and
    toolstack.

commit 2649612686f968a52ce53d173f5c2a3088ad17dd

    tools/libxl: Don't prepare or save xc_config when soft resetting a domain
    
    xc_config is only used by xc_domain_create(), but by calling
    libxl__arch_domain_{prepare,save}_config() we clobber the real settings with
    the default settings.
    
    Move all data and calls relating to xc_domain_create() into the path which
    calls it.
    
    As far as I can tell, soft_reset has always been broken for ARM domains 
using
    LIBXL_GIC_VERSION_DEFAULT, which elicits a hard error out of
    libxl__arch_domain_save_config(), and only works on x86 because this 
function
    is a no-op.

    libxl__arch_domain_save_config().  Prepare xc_config on 
libxl__domain_make()'s
    stack, and drop the parameter.
