Hi Joe,

We cannot use acpi.h since it is an ACPICA header.  Creating
acpi_utils.h sounds good idea.  However, in line 40 of acpi_bus.h, it
has the following comment and declares multiple utility interfaces.

====
/* acpi_utils.h */
acpi_status
acpi_extract_package(union acpi_object *package,
                struct acpi_buffer *format, struct acpi_buffer *buffer);
  :
====

This looks to me that there was acpi_utils.h before, but someone had
merged it into acpi_bus.h for some reason.  This change was made before
the initial git repository was created, so I cannot check the change
log.  So, as of today, acpi_bus.h seems to be the place to declare ACPI
utility interfaces for ACPI core.

Thanks,
