Subject: [PATCH v2 0/2] KVM: arm64: Support for Arm v8.8 memcpy instructions in KVM guests

Hi,

This is v2 of the series to allow using the new Arm memory copy instructions
in KVM guests. See v1 for more information [1].

Changes in v2:
 - Dropped HCRX_EL2 vcpu field
 - Rebased onto v6.6-rc2

Thanks,
Kristina
