Subject: [PATCH v3 11/21] KVM: arm64: Allow populating software bits
Date: Thu, 29 Jul 2021 14:28:08 +0100	[thread overview]
Message-ID: <20210729132818.4091769-12-qperret@google.com> (raw)
In-Reply-To: <20210729132818.4091769-1-qperret@google.com>

Introduce infrastructure allowing to manipulate software bits in stage-1
and stage-2 page-tables using additional entries in the kvm_pgtable_prot
enum.

This is heavily inspired by Marc's implementation of a similar feature
in the NV patch series, but adapted to allow stage-1 changes as well:
