Subject: [PATCH v2 tip/core/rcu 02/39] rcu: Make arch select smp_mb__after_unlock_lock() strength
Date: Mon, 17 Apr 2017 16:44:49 -0700	[thread overview]
Message-ID: <1492472726-3841-2-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20170417234452.GB19013@linux.vnet.ibm.com>

The definition of smp_mb__after_unlock_lock() is currently smp_mb()
for CONFIG_PPC and a no-op otherwise.  It would be better to instead
provide an architecture-selectable Kconfig option, and select the
strength of smp_mb__after_unlock_lock() based on that option.  This
commit therefore creates ARCH_WEAK_RELEASE_ACQUIRE, has PPC select it,
and bases the definition of smp_mb__after_unlock_lock() on this new
ARCH_WEAK_RELEASE_ACQUIRE Kconfig option.
