    xen/ACPI: Drop local acpi_os_{v,}printf() and use plain {v,}printk()
    
    Now that Xen has a real vprintk(), there's no need to opencode it locally 
with
    vsnprintf().  Redirect the debug routines to the real {v,}printk() and drop
    the local acpi_os_{v,}printf() implementations.
    
    Amongst other things, this removes one arbitrary limit on message size, as
    well as removing a 512 byte static buffer that ought to have been in
    __initdata given that is private to an __init function.
    
    No functional change.
