Just the linux-specific changes are appropriate. We will remove a whole
batch of unused exceptions in ACPICA soon. AE_BAD_ADDRESS was one of
them.

>The AE_BAD_ADDRESS exception code is now unused in ACPICA.
>For linux, it's only used at wmi.c and acer-wmi.c.
>I checked both wmi.c and acer-wmi.c, the AE_BAD_ADDRESS exception code
>has no special meaning. The parent functions just call AE_SUCCESS() or
>AE_FAILURE() to check the return status.
>So it's safe to replace AE_BAD_ADDRESS with AE_ERROR.
