Pull MIPS updates from Thomas Bogendoerfer: - added support for Nintendo N64 - added support for Realtek RTL83XX SoCs - kaslr support for Loongson64 - first steps to get rid of set_fs() - DMA runtime coherent/non-coherent selection cleanup - cleanups and fixes * tag 'mips_5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: (98 commits) Revert "MIPS: Add basic support for ptrace single step" vmlinux.lds.h: catch more UBSAN symbols into .data MIPS: kernel: Drop kgdb_call_nmi_hook MAINTAINERS: Add git tree for KVM/mips MIPS: Use common way to parse elfcorehdr MIPS: Simplify EVA cache handling Revert "MIPS: kernel: {ftrace,kgdb}: Set correct address limit for cache flushes" MIPS: remove CONFIG_DMA_PERDEV_COHERENT MIPS: remove CONFIG_DMA_MAYBE_COHERENT driver core: lift dma_default_coherent into common code MIPS: refactor the runtime coherent vs noncoherent DMA indicators MIPS/alchemy: factor out the DMA coherent setup MIPS/malta: simplify plat_setup_iocoherency MIPS: Add basic support for ptrace single step MAINTAINERS: replace non-matching patterns for loongson{2,3} MIPS: Make check condition for SDBBP consistent with EJTAG spec mips: Replace lkml.org links with lore Revert "MIPS: microMIPS: Fix the judgment of mm_jr16_op and mm_jalr_op" MIPS: crash_dump.c: Simplify copy_oldmem_page() Revert "mips: Manually call fdt_init_reserved_mem() method" ...
