c369b3b021
of AML interpreter.
- Delete and cleanup a lot of almost duplicated code in kernel/userland.
- Add new common functions for kernel/userland code.
aml_adjust_readvalue(), aml_adjust_updatevalue(),
aml_region_handle_alloc(), aml_region_handle_free() and
aml_region_io().
- Add primitive functions for both versions of kernel/userland in order to
have shared code as much as possible.
aml_region_read_simple(), aml_region_write_simple(),
aml_region_prompt_read(), aml_region_prompt_write() and
aml_region_prompt_update_value().
- Consider update rule and access type in field flags. Also add a lot of
definitions for the flags.
- Fix bugs on bit manipulation for read/write operations.
- Fix bugs on IndexField I/O part. Also add workaround for temporary
object corruption during StoreOp interpretation.
