Re: [PATCH] Tables: Restore old behavor to favor 32-bit FADT addresses.

[Rafael J. Wysocki]

Hi Lv,

There was a merge conflict with the new ACPICA material queued up for 3.16
related to this.

Can you please have a look at the linux-next branch in my tree and see if
the ACPICA material in there is in a good shape?

Rafael
