Subject: [RFC PATCH v2 03/31] KVM: arm/arm64: Remove unused params in mmu functions
Date: Mon,  2 Oct 2017 22:10:45 -0500	[thread overview]
Message-ID: <1507000273-3735-1-git-send-email-jintack.lim@linaro.org> (raw)

From: Christoffer Dall <christoffer.dall@linaro.org>

stage2_flush_xxx functions take a pointer to the kvm struct as the first
parameter but they are never used. Clean this up before modifying mmu
code for nested virtualization support.
