Subject: [PATCH 38/59] KVM: arm64: nv: Unmap/flush shadow stage 2 page tables
Date: Fri, 21 Jun 2019 10:38:22 +0100 [thread overview]
Message-ID: <20190621093843.220980-39-marc.zyngier@arm.com> (raw)
In-Reply-To: <20190621093843.220980-1-marc.zyngier@arm.com>
From: Christoffer Dall <christoffer.dall@linaro.org>
Unmap/flush shadow stage 2 page tables for the nested VMs as well as the
stage 2 page table for the guest hypervisor.
Note: A bunch of the code in mmu.c relating to MMU notifiers is
currently dealt with in an extremely abrupt way, for example by clearing
out an entire shadow stage-2 table. This will be handled in a more
efficient way using the reverse mapping feature in a later version of
the patch series.
