[PATCH 0/4 V2] ACPI: procfs/sysfs/debugfs code cleanup

[Zhang Rui]

This patch set mainly cleans up the ACPI procfs/sysfs/debugfs code.

1. removes the deprecated ACPI procfs I/F, including
   /proc/acpi/debug_layer
   /proc/acpi/debug_level
   /proc/acpi/info
   /proc/acpi/dsdt
   /proc/acpi/fadt
   because the sysfs I/F has been working for years w/o any problems.

2. introduce drivers/acpi/sysfs.c, code for ACPI sysfs I/F, including
   /sys/module/acpi/parameters/debug_layer,
   /sys/module/acpi/parameters/debug_level,
   /sys/module/acpi/parameters/trace_method_name
   /sys/module/acpi/parameters/trace_debug_layer
   /sys/module/acpi/parameters/trace_debug_level
   /sys/module/acpi/parameters/trace_state
   /sys/module/acpi/parameters/acpica_version,
   /sys/firmware/acpi/interrupts/*,
   /sys/firmware/acpi/tables/*,
   is moved to this file.

3. introduce drivers/acpi/debugfs.c, code for ACPI debugfs I/F, i.e.
   /sys/kernel/debug/acpi/custom_method, is moved to this file.
   And also make the ACPI debugfs I/F always built in,
   even when CONFIG_ACPI_DEBUG is cleared.

4. introduce module parameter acpi.aml_debug, which is an enhancement of
   the runtime custom method overriding mechanism.

any comments are welcome.

thanks,
