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.
