Subject: [PATCH v2 03/18] arm/arm64: KVM: Remove hyp_kern_va helper
Date: Thu, 30 Jun 2016 18:40:36 +0100	[thread overview]
Message-ID: <1467308451-13365-4-git-send-email-marc.zyngier@arm.com> (raw)
In-Reply-To: <1467308451-13365-1-git-send-email-marc.zyngier@arm.com>

hyp_kern_va is now completely unused, so let's remove it entirely.
