ACPI: Enable build of AML interpreter debugger
This patch enables ACPICA debugger files using a configurable CONFIG_ACPI_DEBUGGER configuration item. Those debugger related code that was originally masked as ACPI_FUTURE_USAGE now gets unmasked. Necessary OSL stubs are also added in this patch: 1. acpi_os_readable(): This should be arch specific in Linux, while this patch doesn't introduce real implementation and a complex mechanism to allow architecture specific acpi_os_readable() to be implemented to validate the address. It may be done by future commits. 2. acpi_os_get_line(): This is used to obtain debugger command input. This patch only introduces a simple KDB concept example in it and the example should be co-working with the code implemented in acpi_os_printf(). Since this KDB example won't be compiled unless ENABLE_DEBUGGER is defined and it seems Linux has already stopped to use ENABLE_DEBUGGER, thus do not expect it can work properly. This patch also cleans up all other ACPI_FUTURE_USAGE surroundings accordingly. 1. Since linkage error can be automatically detected, declaration in the headers needn't be surrounded by ACPI_FUTURE_USAGE. So only the following separate exported fuction bodies are masked by this macro (other exported fucntions may have already been masked at entire module level via drivers/acpi/acpica/Makefile): acpi_install_exception_handler() acpi_subsystem_status() acpi_get_system_info() acpi_get_statistics() acpi_install_initialization_handler() 2. Since strip can automatically zap the no-user functions, functions that are not marked with ACPI_EXPORT_SYMBOL() needn't get surrounded by ACPI_FUTURE_USAGE. So the following function which is not used by Linux kernel now won't get surrounded by this macro: acpi_ps_get_name() Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J.
