But how do we get there? The majority of architectures define BUG() already, but a lot of them only if CONFIG_BUG is enabled. That is of course trivial do change, and it is what my older patch does for ARM and x86.
We also have seven architectures without a BUG() implementation (c6x, m32r, meta, microblaze, score, sh, unicore32) and six more (arm64, hexagon openrisc tile um xtensa) that have no bug.h at all.
