[Qemu-arm] [PATCH RESEND v15 07/10] KVM: Move related hwpoison page functions to accel/kvm/ folder |
Date: |
Thu, 8 Nov 2018 02:29:46 -0800 |
kvm_hwpoison_page_add() and kvm_unpoison_all() will be used both
by X86 and ARM platforms, so move these functions to a common
accel/kvm/ folder to avoid duplicate code.

Address Peter's comments to move related hwpoison page function to
accel/kvm folder in [1]
Address Paolo's comments to move HWPoisonPage definition back to
accel/kvm/kvm-all.c
