Add a new UACPI_ADDRESS_SPACE_HANDLER_DEFAULT flag, which all builtin address space handlers register themselves with, thus allowing us to tell which ones are default, and which are installed by the host. This will be used in the future commits. Signed-off-by: Daniil Tatianin <99danilt@gmail.com>
We don't need to lock anything nor jump inside a different function if the space we're given doesn't require _REG calls. Do the check before we do anything. Also add this check to uninstall_address_space_handler (the final caller of reg_or_unreg_all_opregions that didn't have an early check). With that, we can now drop the check inside, which is now redundant. Signed-off-by: Daniil Tatianin <99danilt@gmail.com>
Only do this for builtin handlers, which we can now distinguish from host's via the new flag. Signed-off-by: Daniil Tatianin <99danilt@gmail.com>
These are redundant in that they can be fully implemented internally in terms of already existing kernel API, so get rid of them. Signed-off-by: Daniil Tatianin <99danilt@gmail.com>
