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
AE_INFO,
 * 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)

Great!  Can I consider it as Ack? :)
