Subject: [PATCH v3 0/2] KVM: arm64: nv: Shadow S2 life-cycle fixes
Date: Fri, 21 Aug 2026 17:18:27 +0100	[thread overview]
Message-ID: <20260821161829.1032561-1-maz@kernel.org> (raw)

This is the (hopefully) last revision for this set of fixes for the
shadow S2 life cycle.

* From v2 [1]

  - Fixed the nonsensical type used for allocating the nested S2
    array, switching to kvmalloc_objs() in the process, guaranteeing
    some level of type checking

  - Dropped the extra S2 freeing after Wei-Lin pointed out that we are
    guaranteed to run the MMU notifier release callback, ensuring that
    nothing is left behind

  - Collected AB from Lorenzo, with thanks.
