Greg,

Can you please put this one into stable

	935a9fee51c945b8942be2d7b4bae069167b4886

actually,  even still need to apply to 2.6.32 stable

but commit description could be some different:

for 2.6.32, and kernel before memblock is supported in x86:
Even we call reserve_ibft_region() in x86 setup_arch() some late, but
it still in early stage.
at that time, acpi table is mapped for temporal use and will be
unmapped after handler is called
So handler should not store remapped address for late use.

only after init_main()/early_acpi_init(), we can store those remapped
address for acpi tables in handles

Thanks

Yinghai
