Function acpi_os_initialize1() calls acpi_osi_setup_late() which is in .init.text section and gets called from acpi_bus_init which is in .init.text section. So mark acpi_os_initialize1() with __init. And declaration of __init acpi_osi_setup_late has been removed, cause its defination is above called function. WARNING: drivers/acpi/acpi.o(.text+0x460): Section mismatch in reference from the function acpi_os_initialize1() to the function .init.text:acpi_osi_setup_late() The function acpi_os_initialize1() references the function __init acpi_osi_setup_late(). This is often because acpi_os_initialize1 lacks a __init annotation or the annotation of acpi_osi_setup_late is wrong.
