sparc32: enable different preemptions models
While chasing following warning from kconfig I noticed that the
kconfig preemption model symbols were all dependent on sparc64.
warning: (PREEMPT && DEBUG_ATOMIC_SLEEP) selects PREEMPT_COUNT which has unmet direct dependencies (SPARC64)
>From arch/sparc/Kconfig:
if SPARC64
source "kernel/Kconfig.preempt"
endif
But looking a bit closer I see nothing obvious why
sparc32 should not support the various preemption models.
Drop the "if SPARC64" conditional to enable selection of
preemption model on sparc32 too.
Build-tested - but not run-time tested all three models.
