bitkeeper revision 1.1389.17.1 (42823056RNtq4AlseRHL98DJV2uJgA)

Change the Xen command-line parameter syntax. 'noacpi' and
'ignorebiostables' are gone. 'dom0_mem' can optionally take a k/m/g
suffix to specify units (default units are still kilobytes).

Also added:
 1. 'mem=xxx' to specify maximum physical RAM address (supports
     k/m/g suffix)
 2. acpi=xxx/acpi_skip_timer_override/noapic: These all have same
    semantics as in Linux. They are *automatically* propagated to
    the domain0 command line, as dom0 shares resposibility for
    platform initialisation.
