[Qemu-devel] [PATCH v9 2/7] virtio-pmem: Add virtio pmem driver
...ed-by tag, but you can take my acked-by + tested-by.

Regression with "arm64: KVM: Skip MMIO insn after emulation" on 4.4 stable
Hello, In my testing of crosvm[1] with Linux 4.4.175, I am observing failures on a 'kevin' Chromebook (RK3399) device - the guest kernel does not even get to the point of printing its first messages, and the host seems to be spinning at 100% CPU in KVM_RUN.
