Subject: [PATCH v2 0/4] kvm-arm64: Fix PMU reset values (and more)
Date: Mon, 19 Jul 2021 13:38:58 +0100 [thread overview]
Message-ID: <20210719123902.1493805-1-maz@kernel.org> (raw)
This is the second version of the series initially posted at [1].
* From v1:
- Simplified masking in patch #1
- Added a patch dropping PMSWINC_EL0 as a shadow register, though it
is still advertised to userspace for the purpose of backward
compatibility of VM save/restore
- Collected ABs/RBs, with thanks
