Function trace is most of the ACPI_DEBUG costs, but is not much of use for kernel ACPI debugging. Size of kernel image increased on test compile: + 48k (Full ACPI_DEBUG) + 35k (ACPI_DEBUG with function trace compiled out) Performance without function trace is also much better. Also remove ACPI_LV_DEBUG_OBJECT from default debug level as a lot vendors let Store (value, debug) in their code and this might confuse users when it pops up in syslog.
