   # HEAD: e7b66d16fe41722350ba87f5788052ef53ee28bb x86/acpi, x86/boot: Take RSDP address for boot params if available

This tree extends the x86 boot protocol to include an address for the 
RSDP table - utilized by Xen currently. Matching Grub2 patches are 
pending as well. (Juergen Gross)

 Thanks,

	Ingo
