Hi Joe,

I agree with you. Unfortunately, the ACPI CA (ACPI FW interpreter)
already uses them for its internal-use as follows, so I needed to come
up with some other name... Hence, acpi_pr_<level>.

* Error reporting. Callers module and line number are inserted by
* the plist contains a set of parens to allow variable-length lists.
* These macros are used for both the debug and non-debug versions of
the code.
#define ACPI_INFO(plist) acpi_info plist
#define ACPI_WARNING(plist) acpi_warning plist
#define ACPI_EXCEPTION(plist) acpi_exception plist
#define ACPI_ERROR(plist) acpi_error plist
#define ACPI_DEBUG_OBJECT(obj,l,i) acpi_ex_do_debug_object(obj,l,i)
