Rename the user-visible option so that users with CONFIG_SLAB=y get a new prompt with explanation during make oldconfig, while make olddefconfig will just switch to SLUB. In all defconfigs with CONFIG_SLAB=y remove the line so those also switch to SLUB. Regressions due to the switch should be reported to linux-mm and slab maintainers.

It is disabled since commit 1be01d4a5714 ("driver: base: Disable CONFIG_UEVENT_HELPER by default") as its dependency (UEVENT_HELPER) was made default to 'n', 2. It is not recommended (help message: "This should not be used today [...] creates a high system load") and was kept only for ancient userland, 3. Certain userland specifically requests it to be disabled (systemd README: "Legacy hotplug slows down the system and confuses udev").

And commit 0181307abc1d ("ALSA: seq: Reorganize kconfig and build") reorganised things, which causes the churn.

Verified that the before and after generated configs are exactly the same. Which begs the question why update them? The answer is that it can be confusing when the stored defconfig drifts too far from the generated result. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
