Merge tag 'powerpc-6.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull powerpc updates from Michael Ellerman:

 - Remove support for 40x CPUs & platforms

 - Add support to the 64-bit BPF JIT for cpu v4 instructions

 - Fix PCI hotplug driver crash on powernv

 - Fix doorbell emulation for KVM on PAPR guests (nestedv2)

 - Fix KVM nested guest handling of some less used SPRs

 - Online NUMA nodes with no CPU/memory if they have a PCI device
   attached

 - Reduce memory overhead of enabling kfence on 64-bit Radix MMU kernels

 - Reimplement the iommu table_group_ops for pseries for VFIO SPAPR TCE
