Cover letter [patch 0/2] ACPI: generic initramfs table override support #3

This patch set contains two patches:

1) Move populate_rootfs back to start_kernel, so it can be used by acpi_early_init
2) Add the ability to override ACPI tables from the initramfs

I'd like some review for the second patch. I expect objections to what is essentially open coding the top of acpi_load_table in a separate function, but Jan Beulich advised me that modifying code under acpica/ was not recommended. Ideally there would be a way to replace an existing table before it is loaded, or at the very least be able to request the table descriptor instead of just the table header.

I've tested this patch set successfully at home, but I don't have a particularly exotic setup.

Thanks!

-Jeff
