From 17c46a6aff5c423f406adfb06eb832f771c06bd1 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 31 Jul 2018 13:39:29 +0200 Subject: kconfig: remove duplicate SWAP symbol defintions microblaze and nios2 define their own always n SWAP symbols. Remove those and let the generic defintion do the right thing by adding a new symbol to disable swap entirely.

Note that with this the inclusion of arch/$(SRCARCH/Kconfig moves out of the top-level Kconfig into arch/Kconfig so that don't violate ordering constraits while keeping a sensible menu structure.

For two architectures that means moving their arch-specific symbols in that menu into a new arch Kconfig.debug file, and for a few more creating a dummy file so that we can include it unconditionally. Also move the actual 'Kernel hacking' menu to lib/Kconfig.debug, where it belongs.
