Subject: [PATCH v5 00/21] KVM: arm64: Rewrite page-table code and fault handling
Date: Fri, 11 Sep 2020 14:25:08 +0100 [thread overview]
Message-ID: <20200911132529.19844-1-will@kernel.org> (raw)
It's me again, with version five of the KVM page-table rework previously
seen at:
v1: https://lore.kernel.org/r/20200730153406.25136-1-will@kernel.org
v2: https://lore.kernel.org/r/20200818132818.16065-1-will@kernel.org
v3: https://lore.kernel.org/r/20200825093953.26493-1-will@kernel.org
v4: https://lore.kernel.org/r/20200907152344.12978-1-will@kernel.org
Changes since v4 include:
* Add comments to the kerneldoc describing alignment behaviour for
addresses and size parameters
* Fix formatting of IPA size messages
* Fix handling of unaligned addresses in kvm_phys_addr_ioremap()
* Add DSB after zeroing stage-2 PGD pages
* Add reviewer tags
Once again, thanks to Alex, Gavin and Andrew for their comments.
Will
