Did anything happen with this, or did it get stuck?
We just had another user hit it in Gentoo at

It looks like openembedded (obviously given the author) and Alpine have

The last byte of the option vector was missing due to an off-by-one
error. Without this fix, client architecture support negotiation will
fail because the last byte of option vector 5, which contains the MMU
support, will be missed.

Use the new ioctl, KVM_PPC_GET_RMMU_INFO, to fetch radix MMU
information from KVM and present the page encodings in the device tree
under ibm,processor-radix-AP-encodings. This provides page size
information to the guest which is necessary for it to use radix mode.

Because KVM cannot support radix and hash modes concurrently, QEMU can
avoid allocating a hash page table if KVM supports radix mode.

Both radix and hash modes require guests to use
h_register_process_table() to set up the MMU. Implement it using the
new KVM ioctl KVM_PPC_CONFIGURE_V3_MMU.
This hypercall is also necessary for fully emulated guests, so it will
need to be reworked to integrate with Suraj's TCG patchset.

Does this seem correct?
Should I send a patch even though it's a very small change?

Looks good to me.

then kexecs to a new kernel
and an NMI is received before the new kernel has registered it's
handler, won't QEMU cause the guest to jump to the old, now invalid,
handler address? Is this worth worrying about?
