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()
