[PATCH v3 5/9] powerpc: Rely on generic printing of preemption model.

From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
Date: 2025-02-12 13:41:34
Also in: linux-rt-devel, lkml
Subsystem: linux for powerpc (32-bit and 64-bit), the rest · Maintainers: Madhavan Srinivasan, Michael Ellerman, Linus Torvalds

After the first printk in __die() there is show_regs() ->
show_regs_print_info() which prints the current
preemption model.

Remove the preempion model from the arch code.
