Subject: [RFC PATCH v2 03/31] KVM: arm/arm64: Remove unused params in mmu functions

From: Christoffer Dall <christoffer.dall@...aro.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.
