Subject: Re: [PATCH v9 03/18] KVM: arm/arm64: select IRQ_BYPASS_MANAGER

Hi Feng,

There is a compilation issue for arm64 I need to fix here. Shall I
resend the pre-requisite series or do you prefer to remove that patch
file from this series. It would be included later when arm irq
forwarding series get's ready.

Best Regards

Eric
