From a0d84a92df43b7206b9c1330a2cccf109cf0a41a Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 7 Nov 2008 16:58:05 -0700 Subject: ACPI: update debug parameter documentation Reformat acpi.debug_layer and acpi.debug_level documentation so it's more readable, add some clues about how to figure out the mask bits that enable a specific ACPI_DEBUG_PRINT statement, and include some useful examples. Move the list of masks to Documentation/acpi/debug.txt (these are copies of the authoritative values in acoutput.h and acpi_drivers.h).
