Merge tag 'powerpc-5.13-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates and fixes from Michael Ellerman: "A bit of a mixture of things, tying up some loose ends. There's the removal of the nvlink code, which dependend on a commit in the vfio tree. Then the enablement of huge vmalloc which was in next for a few weeks but got dropped due to conflicts. And there's also a few fixes. Summary: - Remove the nvlink support now that it's only user has been removed. - Enable huge vmalloc mappings for Radix MMU (P9). - Fix KVM conversion to gfn-based MMU notifier callbacks. - Fix a kexec/kdump crash with hot plugged CPUs. - Fix boot failure on 32-bit with CONFIG_STACKPROTECTOR. - Restore alphabetic order of the selects under CONFIG_PPC. Thanks to: Christophe Leroy, Christoph Hellwig, Nicholas Piggin, Sandipan Das, and Sourabh Jain" * tag 'powerpc-5.13-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: KVM: PPC: Book3S HV: Fix conversion to gfn-based MMU notifier callbacks powerpc/kconfig: Restore alphabetic order of the selects under CONFIG_PPC powerpc/32: Fix boot failure with CONFIG_STACKPROTECTOR powerpc/powernv/memtrace: Fix dcache flushing powerpc/kexec_file: Use current CPU info while setting up FDT powerpc/64s/radix: Enable huge vmalloc mappings powerpc/powernv: remove the nvlink support
