I think I found what is causing that.
Commit aa9aaa4d61c0048d3faad056893cd7860bbc084c is moving
definition of Linux's ACPI_DEBUG_DEFAULT to incude/acpi/platform/aclinux.h ,
however include/acpi/acpi.h didn't got updated and ACPI_DEBUG_DEFAULT now
being always defined as (ACPI_LV_INIT | ACPI_LV_DEBUG_OBJECT |
ACPI_LV_EVALUATION | ACPI_LV_REPAIR)
BR,
Gabriel C
