Subject: Re: [PATCH 07/26] KVM: arm64: Add a level hint to __kvm_tlb_flush_vmid_ipa
Date: Thu, 7 May 2020 16:08:43 +0100	[thread overview]

The level feels like a good opportunity for an enum to add some
documentation from the type.

With the constants from the next patch brought forward, the magic 0 can
be given a name, although it's very temporary so..

Otherwise, looks good.
