Subject: [PATCH 21/21] arm64: KVM: Remove weak attributes
Date: Mon, 16 Nov 2015 13:11:59 +0000	[thread overview]
Message-ID: <1447679519-17888-22-git-send-email-marc.zyngier@arm.com> (raw)
In-Reply-To: <1447679519-17888-1-git-send-email-marc.zyngier@arm.com>

As we've now switched to the new world switch implementation,
remove the weak attributes, as nobody is supposed to override
it anymore.
