Subject: [PATCH v2 0/2] KVM: arm64: nv: Reduce FP/SVE overhead on exception/exception return

From: Marc Zyngier <[email-masked]>
Date: Wed, 20 May 2026 09:50:34 +0100

This is the second version of this short series optimising away a lot
of unnecessary FPSIMD/SVE context switch with NV.

* From v1 [1]:

  - New commit message on patch #2 (Mark)

  - Additional comments and WARN_ON_ONCE() (Mark)

If nobody screams, I'll stick that into -next.

Thanks,

	M.
